Heatkiller :)
is the backplate needed? http://www.sidewindercomputers.com/hk1366plate.html
Either the Heatkiller 3.0 or the EK supreme LT ;)
I've heard a few horror stories about the Heatkiller, I'd say GTZ and <S>Taco</S> EK Supreme LT.
Yes the backplate is needed... you need to screw your block into something.
What horror stories have you heard about the HK 3.0?
I agree that HK 3.0 and Supreme LT are very good choices. Also very much worth considering: Enzotech Sapphire Rev. A.
I would also like to hear about these horror stories. Please elaborate.
Haven't we been down this road before? They are all good. They are also all horrible.
When in doubt, buy ThermalTake!
D-Tek Fuzion V2 works well for me with the new 1366 pro mount its really easy to fit, Un fit, Fit and unfit etc. Fans are all near silent BTW

EK supreme with backplate
I definitely like the look of the HeatKiller, but I'm going to be using a GTZ on my SunTzu build. Hopefully I'll have temps tonight :)
where did you get that info about the gtz being the best? the gtz sucks...
the ek supreme beats the gtz in martins review...skinne's review will show that too..and Hesmelaughs review shows the gtz trails the supreme...even i tested it...
read the reviews...
some are in the stickies and some aren't stickied good luck finding them. or i hope someone links it.
if you want the best for the i7, read the reviews. oh yeah read gabe's review, alot like that review :ROTF:

those are not good temps at all my friend. Mine are 10c higher at full load with 1.39v volts. looking that you are using only 1.26v and not at full load... My iddle temps are 34c-36c again using 1.39v.
You should not be bragging about your setup or reccomending it at all. Kind of missleading.
[IMG]http://img5.imageshack.us/img5/6007/overclocko.jpg[/IMG]
You have HT off... better temp in Full because of HT disabled... Try with HT enabled and you'll see your temps jump.
Oh, and what's your room temperature?
The other poster also explicitly said his fans are running near silent.
There's no magic sauce that makes a water cooling loop perform well if you've got weak fans on your radiator. Everyone water cools for different reasons. Personally I water cool for silence and my temps are not very good, but they're a heck of a lot better than if I was running ~800RPM fans on air.
He's happy with his results so I don't really see the problem.
Anyone who says X brand block is the best and all trail X brand block is talking through their exhaust catalytic convertor. The single biggest influencing factor for all of you is how a block looks, and most of you don't even have the gumption to admit that. The tests are more often than not driven by preconceived notions and agenda strewn.
From the reviews I've seen (as mentioned by hondacity), the GTZ consistently performs a couple of degrees "worse" than several of those mentioned. HOWEVER ... it is extremely easy to mount, and that may be important to some. I like it because I can change out my loop or reseat the block without having to get to the back of the motherboard.
Very true, however my CPU is the only block in that loop, so as far as I have seen/read. 350 is the "best" block for my setup.
People need to start phrasing there post from "What's the best block" to "What's the best block for me".
If you want to do a multi block loop, 350 would be a foolish choice. HK or LT would be the way to go.
Doesn't the HK 3.0 outperform the 350 on i7 as well? I'm pretty sure there was a review that showed that.
this?
http://www.hardwareluxx.de/community...d.php?t=590183
go ahead read his review...its very entertaining...oh yeah believe that its true....:ROTF:
wait till you see my triple sli and k350 in one loop, with one pump and one rad..and ultra silent :D
i hate photobucket..i cant upload the good stuff...anyways this just finished today :)
http://i24.photobucket.com/albums/c5...y25/hondaa.jpg
watercool HK ftw !
I find it interesting that this user report of AC350 vs HK3.0 is showing a similar trend to my own test results. I also find it interesting that your stance then is to try to discredit this report by laughing, just like your stance in an earlier post (http://www.xtremesystems.org/forums/...5&postcount=15) about the GTZ was to discredit my own test results by stating that people “liked” my review ROTFL
As to mounting the AC350 better than the GTZ, give me a break. No spring tension limiter?
Performance wise, there are 3 top blocks on the market today, the HK, the GTZ and the Supreme. From their respective C/W vs flow rate curves (see Hemeslaugh excellent work on these curves), we can see that the GTZ tends to favor high flow rates (US market), whereas the other two blocks favor low flow rates (European market).
Which one to choose boils down to setup type, cosmetics, price, and ease of use; and I will add that in the grand scheme of things even setup type remains arguable since the differences are so minimal that they do not affect operating conditions (O/C). So we are left with cosmetics, price and convenience. Cosmetics are subjective, and cannot be argued; price is objective and depends on the user wallet; ease of use is objective and this is the element we focused on to benefit the vast majority of users.
Heatkiller 3.0 LT.
http://www.xtremesystems.org/forums/...ght=350+review (Thanks Hondacity)
Didn't you do an update with the HK and LT in it as well Hondacity? I cannot seem to find it.
Can't seem to find a review of the HK3.0... can anyone link me?
Shane's data is done with 3/8" tubing and relatively lower flow rates than the US. As a result, the relative temps favor flat curved (c/w vs flow rate) water-blocks. Nothing wrong with that, it's perfectly adapted to European loops. In the US, enthusiasts systematically use higher flow systems with 1/2" tubing. Extend the c/w vs flow rate curves to reach the 1.8 (420 lph) to 2 GPM level (480 lph), and you will see that the top 5 blocks are all within 1C of each other. Take all these blocks and test them on another CPU, and all the results will change again because of shape of IHS (diffferent TIM joint).
When there is no more than 1 or 2 C Delta between the top blocks, you can't say that one sucks simply because you don't like the looks of the product or the company that makes them. C/W's of the top blocks are all in asymptotic mode, i.e. they have reached the limits of what can be done with current technology. The differences observed between these blocks reflect not their respective thermal of hydraulic design, since the technologies employed are by and large very similar, but the quality of the mechanical TIM joint.
good catch 3/8 and 1/2s are equal in my opinion :)
there will be two reviews more, Skinnees and leeghold(leegfold?)
i won't assume anything...
oh yeah 1 or 2 c?, sorry i want the BEST :)
well gabe, I think the gtz would benefit from a slightly deeper pin matrix (emphasis on slightly) and a larger pin matrix area (increasing the size of the block SA wise I think because of the design).
Anyway, I love my GTZ, even though its clogged by feser crap right now ;) its flow is higher than a lot of blocks and it has a great design for convenience and looks :up:
I hate you. :D
But seriously that looks like the bomb!! I have actually considered going back to SLI or CF just for looks since my 22" would benefit from it.
As far as blocks go, if you will be running a CPU only loop then any will get the job done, 2-3 degrees is not going to get you an extra 300Mhz out of a chip. If you are doing a CPU/GPU loop then stay away from the restrictive blocks like the Koolance 350, EK Supreme, etc.. If this is your first time water cooling and I hate to say this, go with the GTZ, easy to mount or the D-Tek V2 with the Pro mount. I can't recommend the Enzotech for the I7 (I do own it) because I do not like the 1366 adapter, it will not allow you to remove the chip once the adapter has been installed. I am personally using the Cuplex DI, but I use my own mount using a backplate, some 6-32 screws and thumb nuts with springs to mount the block. It's simple, easy to use and will work with any block except the Enzotech.
i know many hate me, me don't care :D
here's the beauty of parallel loop on the tri-sli....they'll get the temps evenly...unlike 3 gpu's in series, the last one will have the cpu temp plus the other gpu temps.
i'm here to have fun...like it or not :D
i won't use the gtz, as i said i'll use the k350, flow is sorta overrated in my book.
You are obviously not understanding my point, so let me clarify: with blocks being within 1 or 2C from each other ranking results will change from one IHS to another (@ same heat load). You can only start yelling for a foul ball if you start seeing 4 to 5C's deltas from any test results for these blocks.
I totally agree, I won't use Swiftech if given a choice, this is of course my personnel opinion. I really like those HK's and the way they do SLI or CF. They just look so awesome. And no, I do not hate you, I actually enjoy your honest and objective reviews. You don't say anything "Sucks" as some suggest. You merely point out the pros and cons of what is being tested. Thank you fo all the hard work. Now go build a chiller. :D
Hondacity. We posted at the same time. Although I do not hate you either, just disagree with you on some of the things you have posted.
then you obviously didn't read his post here: http://www.xtremesystems.org/forums/...5&postcount=15
he says: "where did you get that info about the gtz being the best? the gtz sucks..."
so I have to assume that Your "like some suggest" above is directed at me, and as you can see, your comments are misguided.
As to agreeing with me or not, everyone is entitled to their opinion, right or wrong. I will leave the conversation at that, and rejoin my family now. Y'all have a good evening.
i did say sucks...lol
utnorris you lied! lol
oh yeah wait for the gt300 512 shaders vs 240shaders ....well thats not facts yet...but that would be awesome :)
chiller? phase change? ummmmmmmmmmmmmm *****still bios editing my video cards :D
You are correct, I missed that post, so I apologize. However I will standby my point that when he does a review he doesn't slam a block. He might point out the short comings, even emphasize them, but I haven't read one of his reviews where he said block X just plain sucks.
I haven't read the review... can't translate it :)
But isn't it equally interesting that you would imply that there is a problem with the 350's mounting solution? I and many others have been using this same "design" for years, on a variety of Koolance CPU blocks, and it sure seems pretty damn solid, easy to use and well designed, to me. But hey, I am no expert, I'm just a guy playing with this stuff. Of course that I am consistently able to get great temps out of the first install of the block says something to me.
Additionally, as consistent as posters on this forum seem to think that Koolance is at worst in the top 3, even those who were, in the past, adamantly against Koolance products, makes your post a bit less credible.
Let me put it a different way. It's understandable you would want to defend your product line. And your products are for the most part good. But pretending that the Koolance 350 doesn't even qualify for the top three, or has mounting problems when it doesn't, isn't as effective than if you would simply defend the performance of your product on it's merits alone.
Well said.
Giving advice based on your own tests is fine. Claiming a product "sucks" because it performs 1-2 degrees worse than other blocks is a bit much but not out of line. But making insinuations that someones tests are laughable when that person is clearly more than credible and experienced in water cooling is insulting to him and anyone else who performs an honest test and gets different results than you.
Gabe freely and openly allows it to be known he is the owner of Swiftech unlike former and current members on this site who are secretly affiliated with a company and push those companies products under the mask of a mere customer who "swears" the product is the BEST.
Gabe has never made it a secret that h is the owner of Swiftech and he's been a member for quite some time. In addition he knows there are many water cool savy members who can easily perform tests as well, if not better than him so for him to attempt to pass faulty results on the members of this site is a gross insult to him or anyone of average intelligence. Duplicate his exact test and if you get significantly different results, let us know otherwise respect his results as he has respected yours.
The absolute truth. All of the sudden Swiftech has gotten too "mainstream" and too easy for those damn noobs to use so now using a product that is much more difficult to install and doesnt even have an english language website is "cool".
And ease of mounting as well as price and support all need to be taken into account. Is the HK worth the additional $50 with backplate for 2 degrees? Maybe so, but at $50 cheaper and 2 degrees worse, the GTZ is still a top block.
And no, I don't have a GTZ or an HK.
Clearly this is the best i7 block....
http://www.zalman.co.kr/ENG/product/...ad.asp?idx=342
/thread
So... umm yeah I actually am not sure with all the numbers and graphs and links to test results being thrown around. I just have a few simple questions about what I should slap ontop of my own pretty i7 920.
I got a Asus RE2 and want to cool the CPU, Mosfet, Mosfet, NB/SB. I plan on using Koolance NB/SB and I figured since they made it easy use Koolance for the practically everything. The only thing I am unsure on to use Koolance for is the CPU.
Since I am using 13mm koolance tubing and my CPU will be on a loop with the rest of the motherboard it sounds to me a 350 (since it seems to work best by itself and no other blocks... mean 350 doesn't like to play with others :ROTF:) probably would be not the best, and I should go with a 345 (the slightly fatter one that plays well with others).
Now would the HK 3.0 be better with the multitude of blocks in the one loop and will Koolance fittings work, or should I just say with the 345?
Oh just looking to keep my temps at around mid 40s to low 50s at load with maybe a 3.8 to 4.2 OC. I am talking the whole MB not just the CPU.
I know that this is extreme systems and only the "best" will suffice but as a first time lc'er, I really liked the GTZ. Now at the time when I bought my i7, the GTZ was the only block on the market suited for it and available for it in Australia. I can remember people singing praises about it then, which are now on the other side making out that it is rubbish as they have moved on to the new top product following the trend of others. Had other blocks been out at the time I might as easily of chosen a different product, but that wasn't the case, I still think the GTZ is a great block. I would be a hypocrite like many others if I started bad mouthing it now. It may not be the "best" block, but it isn't rubbish.
Kind of off-topic, but backplates. I'm using a noctua cooler now and every cooler now has a backplate and the hoel spacing should be the same for every single one. Could I use it in conjunction with the EK supreme LT? I've orderer one, but no one stocks the backplate for it.
I'm not sure? If the threaded rods on the backplate are long enough and are the right thread pattern for the nut or what ever retains the tenison I would say possibly yes. But in reality I doubt it as other people would probably be doing this and I haven't come across anyone asking before.
oh i do, his tools are legit :yepp:
i'm not sure if the hole is big enough i think the screws that come with the supreme lt is m3 or m4...Quote:

excellent choice btw :up:
Thanks! It'll be a cpu only loop with silly amount of cooling until i can expand with more blocks. screws aren't really a problem. Hardware stores ftw =) I'm just wondering if backplates have any function other than being the fastening point.
Just bling, same base with dif tops. The LC (low cost) version has less fins in base plate so it has worse performance.
I only own one i7 block, so I can't say anything about any other block. I do ave a GTZ though, and I love it!
Easy to install. Wasn't too expensive. Performs great! Looks awesome to me!
Best waterblock? Probably HK 3.0 LT ..
i had a fuzion v1 with temp fittings
but got fed up waiting for retension brackets
then Ek supreme (Too restrictive)
GTZ (Good retensions system but temps 2 to 4 deg higher)
now using HK 3 LT great temps and good flow :up:
definely the best i have used
Heh, better than Thermaltake though.
Seriously though, all waterblocks have their merits. The big issue here is that not everyone tests quite the same which is going to give minor variations in results. You have your hardcore must get that last .5 degree out my system to get it as cold as possible people, and on the other hand you have the more general is it worth an extra $50 for a single degree? The HK, 350 and EK Sup definately appeal to the multi-loop or money is no big deal types, whereas the GTZ and others appeals more to the cooler that is looking at not dropping a bunch of coin on just cooling a CPU.
Different strokes for different folks. Pointing fingers and saying this or that sucks or your testing method sucks, or blah blah blah whatever only pisses people off. Make your statement, say why or what you dont like about something and leave it at that.
And FYI, myself, I dont watercool my personal PC. I run a Xig 1284 EE on a mildly OCed Q9650. However I have assembled 5 different loops for people. A good deal of the stuff I know I learned here, the rest is just common sense. Water cooling is NOT rocket science.
At the moment some numbers : from best till last on a PA 120.3, MCP 655 vario, 10/13mm tubing (sole CPU loop) and ambient 22.5°C
Test was a 2 hour Prime run on all 8 cores with the CPU at 3.8Ghz 1.29Vcore
Vario 2 setting (average coretemps) :
Enzotech Luna rev A : 61°C
Koolance 350 : 62°C
EK supreme : 62°C
XSPC : 62.5°C
Enzotech Phoenix : 62.7°C
Swiftech GTZ : 63°C
OCZ Flow : 64°C
Vario 5 setting :
Koolance 350 : 59°C
Enzotech Luna rev A : 59.5°C
EK supreme : 60°C
Swiftech GTZ : 62°C
XSPC : 62.2°C
Enzotech Phoenix : 62.5°C
OCZ Flow : 63°C
I'm really puzzled with the beta Phoenix blocks results as I'm seeming to be the only one that gets worse results with it then with the older Luna block. Could be IHS related... By the way these are the average coretemps of 3 mounts...
I'm redoing the swiftech GTZ as I've noticed that one screw doesn't tighten down 100% so it might gain a little... (I saw one core getting higher temps in respect of the other screenies)
In my opinion I have to say that there is really not much difference between the top blocks...
There are more blocks on the way and a new flowmeter (my bigng broke down halfway the test)...
sorry i spelled your name/username wrong,
can you add more voltage? with one block can you do temperature scaling say 1.29v ,,,1.35v...1.4v...1.45v 1.5v..1.55(max safe)
wow you had good results with the ek supreme, i'm wondering if the 1.29v isn't really giving out alot of heat, do you have a power meter? or a kill-a-watt?
I can give that a shot mate (maybe with the EK as it's still mounted) My cpu is a real hot head already... one of my better I7 clockers (4.4-4.5Ghz benchable on water) but 4ghz ( 211 x 19 ) prime stable needs around 1.37... When I see some reviewers doing 65°C at 4.2 my cpu seems to be a total dog...
I will have to redo the Swiftech again before publishing the review... I think it can get into a better spot once all screw are properly tightened
I've been in contact with Enzotech and there are new basemounts in test, but the Luna vs Phoenix issue is driving me nuts (I redid the whole tests with another pump at 2 speeds for them and yet came to the same end result) is it the european lower flow that 's is killing it's performance ?
It's very hard to effectively test these blocks (difference in IHS, small variations in ambients, humidity, never 100% remounting possible on some blocks, TIM amount can vary etc etc etc) but again the top blocks are not far apart
FYI I tested all these blocks with the mountings they came with, so some blocks didn't have any backplates on the testing platform.
sorry i don't do low flow:D
you should try the HK3, i had more than 30mounts till i got the good results :D
mounting is the mountain to climb in testing i think.
Normally I have some german blocks on the way next week or so. Vario 5 is a setting I never used on my 24/7 rigs (always 3) Thing is you can never satisfy everybody : some blocks will work more efficient when you have more blocks in the loop, others will work better alone, some better with high flow, double pumps etc....
This makes all these watercooling reviews very hard to analyse... too many (external) factors
its true all setups are unique, or one of a kind, i use my a single pump too on my k350, dual pumps are for benching, i know the 2nd pump would cause a restriction, but flow is overrated.
wow i just realized the k350 is also good even in low flow situations...thanks for your testing Leeghoofd
**my 355 is quiet :D , its got software vibration dampers ...joke :D
You're kidding, right? 30 mounts? And, given it took 30 mounts in your testing to get "the good results," I'm sure you have done as many mounts with the other blocks you've tested and rejected as being inferior to the HK, correct?
If not, why the bias? To not do as many mounts for other blocks you've run, and to do that many on the HK just to get "the good results" smacks of someone pushing an agenda.
Just sayin'..........
i chose the best numbers, others were 1-2c off ..i consider them MY errors in mounting...
30 mounts Honda? I would not have admitted that to anyone. I would have said yeah, got her the first try and did a couple extra to keep things fair...:rofl:
LoL i got new stuff to try, and maybe redo some testing, the weather here is great...temps my stay good :)
This is a critical issue. Please email me your address at gabe@swiftech.com for a replacement backplate.
Optimum performance with the GTZ will be obtained when the following thermal grease imprint can be observed; this is the type of imprint I had for my review. Look at the center. All the grease has been squished out showing and elongated pattern. If you see grease in the center area like you see on the edges, then you have a poor mount.

Does anyone know when skinnee is done with the cpu block test he is working on?
I dont think skinnee knows that himself :D :p:
:sofa:
If you guys only knew how much work is involved. I'm busting hump testing as much as I possibly can and writing reviews while the tests are running. 10+ blocks is a lot of work. I am enjoying the testing and data analysis though.
I want to release an individual reviews and test reports as I go. I will publish the individual reviews to the site and a comparison thread here when all of the as-shipped/per manufacturer instructions are complete.
I wouldn't question his biasness as we should trust he did fair testing. The bigger issue is who the hell would want a water block with such an annoying and complicated mount, which would take an experienced watercooler 30 or so tries to get the "good results" out of the block. I'll take a 1 degree hit in temperatures to save myself gray hairs.
Great, the only place that had the HK 3.0 LT, Performance-pc's, just ran out of stock. And the only other place I found, sidewinder, is OOS as well.
Don't HK's need to be imported?
I picked an Acetal HK 3.0 LC up from performance-pcs yesterday morning. They still have those blocks in stock too. They were out of the HK backplates, but subbed in a dangerden plate. I'm hoping it will work well.
--Matt
I meant what puzzles me is why you would be getting so much deviation because I find the mounting mechanism to be very straight forward. How large were the variations you were seeing?
1°C, not that big a deal then. I'm only running at 1.26V vcore currently.
Yep, I'm loving this cpu. I know that 3.8 GHz is nothing special for these chips but I am still amazed at an almost 1.2 GHz overclock at such a low vcore.
Just caught up on this thread. Am eagerly awaiting skinnee's test results - not because I need a new block (happy with my GTZ), but because I find these testing threads interesting.
QFT^^ You will likely be disappointed with the LC version on an i7.
That's okay, It has to be better than my Fuzion V1. The difference between the LT and LC would probably only be ~1C anyways, right? I was under the impression that the LC is still better than the EK Supreme, which would put it on-par with the similarly priced EK Supreme LT. Am I mistaken?
