View Full Version : D-Tek Uni-sink
Anyone received one and installed one yet? Does it install easily?
I'm a bit upset about the performance of the Stealth (no I haven't tried it yet) and I am considering the alternatives.
Now.. don't flame me.. but I was thinking about the possibility of jerry rigging fans on top of the D-Tek Unisink :)

Hmm... I was actually thinking of doing the same thing.... I havn't seen any numbers on the stealth yet, so it's really that bad? Also, have you heard of anyone using the unisink w/ the MCW60 w/ the G80 adapter?
The numbers for the Stealth are not very promising, with all respect to Gabe.
Basically, its a pretty water block... more pretty than MCW60 + a million non sticking heatsinks.. Very much in the same philosophy as the EK. Pretty.
In a semi-official Gabe release, the observations that the GPU temps were identical to that of a MCW60. Obviously, the MCW60 is a whole lot less restrictive. I was shocked that the drop off is worse than the D-Tek's, to think I had the audacity to laugh at the D-Tek when I saw the pressure drop.
The memory cooling is purported to be pretty effective. Oppainter managed 1200 Mhz on the memory for a GTX. That blows me away. However, its Oppainter were are talking about, and I'm no Oppainter.
In summary, I just spent $220 minus shipping for blocks that perform the same :)
You know what I said about appearances... a turd-looking object that performs well suits me just fine.

I think my brain is going to implode any minute now.
On one hand I want the Stealth, because is bound to out perform my current DD full-cover block (with built in Sloppy Finishİ), and it doesn't involve dealing with a dozen individual HSs like the MCW60.
On the other, I know that my D5 is going to complain in languages not heard on this planet for the last 5000 years the minute I rig it.
So... like you I find myself looking at the Uni-Sink with the corner of my eye and wondering... "What if?".

I don't have an 8800 yet, but I was checking clearance yesterday while taking photos of the Stealth and UNI-Sink/MCW60 side by side... the MCW60/G80 plate + UNI-Sink combination should be fine (the MCW60's G80 plate is a *tiny* bit wider than the FuZion GFX's, but it looks like everything should be fine due to the MCW60 keeping the plate elevated above the only potential clearance issue). I'm planning on going with this setup for my new build--w00t for finally replacing my aging AXP/9800 "gaming" rig :woot:

Mr. Toad, why are you unhappy with your DD full-cover block? Is it the restriction imposed on the rest of your loop, your GPU temps, the impact it has on temps elsewhere in your loop, the quality, the look? I'm curious.

@Ian Y... what are you using today? What are you unhappy with currently?
I guess I still have the old school MCW60 plus a million heatsinks. I am unhappy that the Stealth is not any better performing than the MCW60, even though it has a GT/GTX base. I essentially just spend $220 for two pretty blocks, so that I can get rid of a million heatsinks.
Maybe I'm being too harsh because I haven't tried it yet. The memory cooling is said to be great, so maybe that itself is a redeeming quality.
BTW, for your convenience, here are the Stealth results.

I'm unhappy because is screwed up (hence my "sloppy finish" comment).
The base of the block looks like a picture of the surface of Mars, and I have no means to correct it. Any attempt to lap it, with my (lack of) tools and expertise is going to make it even worse.
The channels are uneven to say the least, and it took a good deal of scrubbing with a toothbrush to get rid of the flakes. This came to my attention shortly after rigging it, when I saw tiny shiny little flakes blissfully travelling through the flow...
And then there's the unnecessary heat dump from the VRegs, memory... I have good airflow in my case and I don't mind an extra fan at all.
Edit: The problem with the block is all my fault. Any QC may let an odd one pass, specially under tight deadlines and surge in demand situations.
DD has a reputation for sorting out customer issues, however, due to unforeseen circumstances, it took me two months since the date of purchase to actually use it and find out about the issues, and when I did I just couldn't be bothered to deal with it.
I'm sure had I made DD aware of it they would have solved it on a satisfactory manner.

We know the Stealth is restictive but is it more restrictive than a EK FC 8800 block?
We know the Stealth is restictive but is it more restrictive than a EK FC 8800 block?
Does that matter? The Stealth provides better temps than the EK block. For now, its MCW60, D-Tek and Stealth on one level, then its EK, then something else, possibly Danger Den. I wonder how the Maze5 would be if it were able to be mounted on a G80.
Now.. what if we put a bazooka amount of head pressure through a Stealth.. like an RD30 or two DDC+ ... maybe the Stealth doesn't do so well with just a D5.
I've had a Uni-sink since Monday to go with the MCW60 that's also been sitting here. If I can get time this weekend to voltmod the GTX I'll get it all installed. First order of business for me is a trial fit to see if the thermal tape can be gotten rid of and Ceramique used instead.

The GFX is supposed to have a huge pressure drop, and if i remember correctly, is only on par with the MCW60 if it's in it's own loop.

Please remember that GPU temps are less important than CPU temps - what I mean is that GPU's run happy up to 90C or so, CPU's do not. I would bet that a vid card GPU running at 40c or 50C would still OC the same... CPU's are different.

Agreed, even if volt modding your GPU, any of the solutions mentioned in this thread (MCW-60, D-Tek GFX, Stealth, EK FCB, DD FCB) will all provide ample temperature headroom. GPU overclocks with water cooling are voltage limited... not temperature limited.
If you are running your CPU in a separte loop than you you might as well pick the block you like the looks of the best since it won't matter one bit, which one you choose as far as overclocking goes.
If you are running your CPU in the same loop, then first, consider a separate loop, and then if that's not possible, choose the block with least restriction... which is likely the MCW-60, although we don't yet have verifiable data on the Stealth.
So IanY, since I suspect your run multiple loops, I'm not sure why you are so conserned about the Stealth's performance. Even if it's perforamnce is not up to that of the MCW-60 and the Uni-sink it won't matter... and it will look better than a turd! :p:
virtualrain
06-08-2007, 01:28 PM
One other thought for those of you who like the looks of the stealth but are not happy with the restriction... Gabe suggested you could mill down the pins on an apogee or MCW-60 plate (not sure which) and use it with the Stealth cover. You could use a dremel and do this and cut the pins down until the cooling/restriction is exactly to your liking.... want ultimate flow?... cut the pins completely off! Your own custom water block!
In summary, I just spent $220 minus shipping for blocks that perform the same :)
I can assure you that if such is your inclination you will see the Stealth really shine in a volt modded card. Other factors in favor of a full coverage solution like Stealth remain system noise reduction, since you don't need a fan to cool the ramsinks & nvio chip, and simplicity of installation.
From a performance standpoint knowing that the MCW60 beat the DD solution by 10C here: http://www.madshrimps.be/?action=getarticle&number=9&artpage=2559&articID=554
and that the Stealth perfoms identically at +/1c from the MCW60, we do feel that we have a fairly decent offering for people who want a full coverage solution: ease of install, superb thermal performance of GPU & Memory, and a price that remains reasonable. I am still waiting for an EK block to measure against so until then, the Stealth might be king of the Hill among full coverage blocks.
We are still working on improving the flow rate. If it is possible to do, we will since after all every little bit counts.
Gabe,
Understood. I need to get going on how to volt mod an 8800 :)

So yes, i will get whatever looks the prettiest, however my next blocks definitely need to have barbs pointing out and not up and down. So most likely i wont be getting FC blocks next time around.
I might just salvage my MCW60's :T
But 2 stealths with my GTX might look the prettiest. I would need to see pics... im suprised no one has posted them yet. :T

Honestly I wish Swiftech would come out with something along the lines of the Dtek Unisink.
Sure, the little ramsinks work fine, except on the nvio chip, (I modded my own to fit on there) and if you use thicker hoses you have to be careful not to knock the little things off.
I just think a 2 piece set ( 1 for the nvio and 1 for the RAM) or a dedicated 1 piece would be ideal for the people who already forked out for the MCW60, without having to buy something from somewhere else.
Im sorry but for the same performance, (Im still performance orientated) why would I want to fork out 100+ for the same block I already have? I think you would sell 10x more of something like I described compared to the Stealth ( I may be wrong).

I bought 2x Apogees 1U for my 8800GTX SLI and I have to say that my GPU temps are excellent. The cards are overclocked to 665 core/1650(around there) shaders but the memory will not do more than 2060 in very intensive games.
I am using MC14 ramsinks and it was a nightmare to fit! I had to sink them in alcohol and remove the thermal adhesive they had on and replace it with better 3M material. But still they are so sensitive that I am afraid to take out the cards from my case!
So a uni sink would be great in the future. Right now I am not wasting any money just to gain even 100Mhz in memory (I doubt it) and maybe 30-40 more in the core and that is with a volt mod.

In order to get more out of your GPU memory, you will likely need to increase voltage (i.e. volt mod) and/or loosen timings... assuming you have good airflow overthose MC14 ramsinks. Improving cooling alone is unlikely to help you.

Hi guys, firstly it fits fine with the Mcw60 there is no problems whatso ever with clearance you can get a cigarete paper between mcw mounting plate and the upright fins on the unisink ;) .However it just touched the fan on my SB so I cut away about 5mm from the inside edge, I do not think this is enough to be detrimental. Camera has a flat battery so it is charging at the moment, so I will add pictures shortly. Temperatures for me with ambients @23c with the system in my sig are as per pic using everest.

Might want to check out (finger test if it's safe) the back of the board around the mem, nvio, and vr chips to just be sure it's taking the heat away. Saddest part about bad full coverage cooling is that the heat ends up seeming ok from the sink side, but turns out to be burning the card up on the back side.
Only mentioning that there's more than gpu temps being covered here. And I'm wondering if the nvio area needs more sink material. And like Starscream, I'm curious how well the ram gets cooled but I know it doesn't get really hot either.
Thanks!

I got the Uni-sink in the other day and although I haven't had a chance to test it I did get it installed on the GPU. I had a problem getting it to mount properly. I was getting a visible gap between my ram and the sink. I eventually fixed the problem by cutting an extra 8800 bracket for the MCW60 and usint it to hold the sink down better around the gpu area. Will post more results when I can test it ( think I have a bad cpu though, so that might be a while. )

Yeah, those thick pads are likely there because the surfaces aren't made to perfection, but it's not like it's hugely $$ either.
But memory temps and nvio temps, and the resulting back of the board temps are going to be interesting to see in action. Meaning in comparison to any of the full coverage systems using thermal paste and to the Enzo sinks using the thin thermal stick stuff (3M?).

We are still working on improving the flow rate. If it is possible to do, we will since after all every little bit counts.
Can I suggest (but you probably have already tested this) but MCW60B performs very well and seems to have great flow with ApogeeGT/-X base :cool:
And I did swapped that MCW60B's base to the Apogee... but yes of course... it needed ~3 mm riser plate between top and base (on GT's case). It's good enough base to cool down my naked C2D-6420.
And IMO it's worth to carve hole-edges of the tops so they are more round.
As noted above, the pads are 0.5mm/0.020" thick. They are not sticky. The Uni-Sink is mounted to the card using the factory mounting and screws.

Anyone who buys this thing be aware that at least on my card, Asus 8800GTX this thing only made contact with like 4 of the memory chips completely installed and tightened down. It also only made good contact with 1/3 of the voltage regulators. I would HIGHLY SUGGEST that you have an extremely hard look at the contact points on this before you throw it in the computer. Later on I will post some pics.

I installed one, and from the look of the clearance, I highly doubt that is an option. Some sort of thermal pad, preferably one with a fair amount of stickiness would work the best. The thermal pads that come with the Uni-Sink are already really thick, and I still had problems with them contacting the ramsinks. As a matter of fact I had to cut a bracket to help hold the Uni-Sink down better. You can see my method in my work log. It's near the top.
I'm waiting on a mobo before I can post any performance specs. I had my 8800GTX stable at 972mhz ram with the ram sinks. So now I will have to compare to the Uni-Sink when I get it all up and running.
Dateranoth
EDIT: On second thought, going the route I did with the bracket, then you could probably get away with some sort of paste. Just have to be careful. I had a VISIBLE gap between some of the ram when I first installed my UNI-SINK.

Just helped out a friend today and we ran into the same problem on one of his cards. We ended up adding another layer of TIM on the thermal pad itself just to get a sticky contact that would keep it in place.

Ok here are some pics:
Taking off my current sinks to install the Dtek
http://premium1.uploadit.org/AngrySteel//USK1.jpg
I always test seating with thermal compound before I ever install anything for 24/7, good thing too because this is absolutely horrible seating. This is after a full installation, with the MCW60/Unisink tightened down.
http://premium1.uploadit.org/AngrySteel//USK2.jpg
And the Unisink, notice the absence of imprints on most of the memory chips, except around the screw holes on the lower row. It makes good contact on the NVIO chip and the 3 outermost VR chips.
http://premium1.uploadit.org/AngrySteel//USK3.jpg
Basically the design is flawed because it really needs to be secured to the 4 center mounts too as in the reference cooler, Im not sure of the Fuzion GFX mountings, maybe they hold it down but on the MCW60 it doesnt. Here was my answer, I was too disappointed to waste more time making a hold down plate. The 2 rubber grommets hold down that thin back area where I dont see 1mm of daylight through the memory chips.
http://premium1.uploadit.org/AngrySteel//USK4.jpg
Other notes, I think its sort of a bad design for other reasons which didnt hit me till I put it in my case, the whole right angle Heatsink fins are pretty much designed for a fan on a side panel. Thicker thermal pads are fine I suppose, but beware tightening down too much, as you can see that there is a lot of pressure on certain points. Well...this is all the time I care to put into this thing, I will use it for awhile until I decide to just epoxy the copper ones back on. :)

Hmmm, it seems I might be be selling mine right after I receive it without even opening it. It doesn't seem like it'll be worth removing the two fans I have pushing air up at the card on each side of my MCW60 for the Uni-sink if it doesn't make good contact with the memory.

Ahhhh! Ok im definitely getting a kit of swiftch's ramsink with some T412 tape for my 8800GTX and MCW60.
Hm.. this blows. I was hoping I could avoid the ramsink hell this time. Blergh.

Has anyone thought of using a bracket of some sort, sandwiched between the lip of the Uni-Sink and the MCW60's mounting post retention nuts? I'm guessing that would fix the problem...but would probably make the Uni-Sink incompatible with the D-Tek FuZion GFX (due to the different mounting hardware).

I actually have already done this. Refer to these pictures :) :

No interference with the MCW60 at all.
This works well with the MCW60s and the thumb screws do clear, but I ended up replacing them with nuts because I THOUGHT they wouldn't due to improper MCW60 assembly. You can read my work log as to why that happened ;)

I hear what some of you guys are saying about zero contact with some of the ram chips and I had the same on the initial fit, but after changing my sequence of tightening the screws I have contact on all pads. I checked very carefully with maglight to see if there was any non-contact and all seemed ok for me! Maybe a bit premature to right it off. Maybe we should just mail D-Tek and ask for some more pads to be mailed out and double it up or advise then to use some thicker stuff like some shinetsu stuff i saw a couple of years ago.

I'm sure we'll have some more people testing as time goes on but this isn't a good sign for some of us. My ramsinks are sticking, and they are on there seemingly just fine. To think of ripping all those off, destroying the nice 3M tape in the process, which is hell to find btw, and then finding out that the Unisink doesn't make proper contact would be no fun at all.
Thicker pads are going to be worse at transferring heat as well. But I suppose it's not like the Unisink is super expensive. Just a bit disappointing is all.
But it's not like the Stealth covers the VR's either, nor do we have anyone yet testing it for good contact, so the options are limited.
Thanks for all the news though. Good pictures and lots of testing sure helps.

Damn! I was hoping that i could avoid resticking all those MC14 after I take out my 2 GTXs for volt modding! The hell with it I am not paying anymore for crap like this. But I hate it that I will start the MC14 hunting all over.

I removed my heatsink yesterday and had a look once more and I can confirm I am getting light pressure on some of the memory chips and innermost vregs, I have applied some Tim and refitted it for the moment. I also e-mailed D-tek regarding this and received a response from Danny saying they were looking into a fix for this! Will post when I know some more.
Guys, any idea if the Uni-Sink fits the GTSes? If so, how much modification is required, if any?

The current version of the Uni-Sink is not compatible with the 8800GTS (the voltage regulator layout is different), it only works with the GTX and the Ultra. However, there is an 8800GTS version in the works.
Cool- Any ETA on the new one? I am probably getting a GTS within a few weeks and will be looking to watercool it.

D-Tek's ETAs have been all over the place lately, so I'm really not sure when it'll be released--I've seen the prototype and that's about it.

I have been thinking a lot about the RAM cooling dilemmas of using a universal GFX block recently. I figured if i took accurate measurements of my 8800 GTS what would be stopping me from asking an aluminium heatsink manufacturer from mocking me up a prototype.
Well, after a 30 minute discussion with an engineer today at such a place i am thinking it might be much harder/costly that i had initially anticipated. It took me about 10 minutes to explain to him why the hell i was using water inside a PC and also why i just didnt use a larger waterblock to cover the RAM as well. :) I finally convinced him that i wasnt mad and was honstely looking for his advice.
His comments:
1. It is actually pretty hard to get a great contact on all RAM modules as they will differ slightly in their heights due to the manufacturing process of the GFX cards. Obviously the base of the heatsink is very flat and will not make contact with all the modules if they are slightly different heights on different cards.
2. Having shown him my design (see below - sorry about the size) and have him pretty much rip it to pieces from a "difficulty to manufacture perspective" i showed him pictures of the D-Tek sink.
He said it looked like it was made via a combination of extrusion (making a mould and pushing the aluminium alloy through this for the desired shape) and milling off the bits you dont want. This is very costly, esp in the UK. He was saying it can cost in the £1000s just to make the mould. Costs for milling an existing heatsink design to the dmiensions of the GTS would be costing around £50-60 a go.
I am not going to give up though as i find the MC14s incredibly fiddly. I have contacted other companies for thier views and if need be i will be buying a relatively compatible 'rectangle' heatsink and milling it myself!

I think my brain is going to implode any minute now.
On one hand I want the Stealth, because is bound to out perform my current DD full-cover block (with built in Sloppy Finishİ), and it doesn't involve dealing with a dozen individual HSs like the MCW60.
On the other, I know that my D5 is going to complain in languages not heard on this planet for the last 5000 years the minute I rig it.
So... like you I find myself looking at the Uni-Sink with the corner of my eye and wondering... "What if?".
You do relize that built in sloppy finish of the DD-fullcover was more than likely done by design don't you. It would create some turbulance which if done correctly is desirable for cooling. But the basic design of the block itself isn't that good.
EKs work is some of the best I have seen on blocks . With 2 changes I could make it the best performing best flowing full cover block on the planet.

I can't comment on the "rough" finish on the channels. Was it intentional? I don't know.
However, the copper flakes, some already loose, others on it's way, which, shy of making a mess with sanding paper, I had to remove using a toothbrush, plus the deep scratches on the surface, both in the memory and the GPU areas, make for a truly sloppy finish.

With all due respect, although I have no reason whatsoever to doubt your skills, I fail to see what this has to do with the Uni-sink itself, or my dilemma between the MCW60 and the Stealth.
Besides, I've already made up my mind, and providing my 8800 is not volt modded, and that the Stealth is nowhere to be seen on this side of the Atlantic, I've gone for the tried and tested MCW60 + MC14s + MC21s route.
As posted many times before by other fellow members, removing the pads from the MC14s, then using regular TIM (MX-1 for me) and two tiny drops of loctite to hold them in place actually does the trick rather nicely.
The contact problems with the Uni-sink described earlier in this thread certainly influenced the final decision.

FYI those pics of the dd8800 block that surfaced a while ago on XS were of a block that was mistakenly sent out from a bad batch (per the response their machinist gave me when i showed him the pics). I have see other dd8800 innards (sorry no pics) and they dont all look like that, the one i saw was very cleanly machined.

I always thought it was wierd that they didn't put many fins over the HSI.....that's the hottest chip of the bunch...but plenty of fins with this new one.

cause all of this is becoming pretty late seeing the 8800 has been out for a good while.

Wow. Is that the real thing or a prototype? If so when is it out?
Looks very much like the one i wanted to get made (see a few posts back) but got told it would cost way too much! :D

Just so nobody gets toooooo excited too quickly, UNISINK WILL NOT WORK ON THE GTS!!!!
It only works on the gtx model.
I contacted them and they are still in the works on a gts prototype, but nothing as of yet

So why all the :banana::banana::banana::banana::banana:ing about ramsinks? Just run atx-b and the ramsinks sit fine. My only :banana::banana::banana::banana::banana: is that swiftech sells the 8800 kit with sinks that wont fit under the 1/2" barbs and i had to sand them down myself!
edit: wow i guess im bananas.

I like this new sink. While the individual sinks work fine, I wasn't happy until I used artic adhesive on them which is permanent.
This new sink appears to address the contact problem around the GPU by incorporating what appears to be GPU bolt down holes also, and it has more fins which I like.
The GPU only blocks perform better than the full coverage blocks, so this is a worthwhile improvement IMO and I would buy it for my next 8800.

nah they wont snap of aslong as you dont try 90 degree bends.
Id make a picture of one of mine if my cam wasnt so crappy.

that was seriously the roughest part of my build. Sanding ramsinks that didnt fit by hand lol. I guess i should be glad.
