ATI 5970 Blocks

[Sadasius]

I waiting to see what the OC'ing is like with a good waterblock first. Did not like some of the reviews for this card and I may end up going with a plain 5870 instead of maybe even a couple of those as they clock nicer. But first I will wait and see. Nice blocks all around guys. Nice to see attention given to the VRM's in this case.

A friend of mine sent me this video:

Haven't had time to see the whole video.
Let me know what you think.

[Crazystang01]

Was a nice video to bad he didn't show a screen shot of the temps in the sensors tab of GPU-Z. Would of been cool to see the temps of the VDDC's and your block EK.

Yea, only showed the GPU temps, which seemed nice at a load of 41 C.

What else is in his loop? I didn't see that in the video either.

[RickCain]

Is it me or does EK, AC, and Koolance all have the GPU fins in different areas?

[Eddy_EK]

Me thinking the same way
We have it exactly above GPU's.

[Shoggy]

Optical illusion

Of course we also have it above the GPUs.

[Eddy_EK]

I was thinking more of the koolance... AC has it on the spot.

True, but you would have to assume given the clocks achieved that the VRM's previously identified as one of the limiting factors in getting the card to 870 clocks, let alone higher than are being serviced by the block. Looking good though I must say. Now do I pull the trigger on one and which one...

[jaredpace]

Hey guys, Your blocks are doing a great job keeping the cores cool, however I suggest you make efficient, direct contact with VRMs for these 5970 cards and get some flow over them (since vrm temp is your/ati's limitation):



1 - 3× Volterra VT1157SFs feed the GPU silkscreened as "U1" (vddc phase 1,2,3 of first 5900 gpu).
2 - 3× Volterra VT1157SFs feed the GPU silkscreened as "U2" (vddc phase 1,2,3 of second 5900 gpu).
3 - 2× Volterra VT1157SFs feed RV870 GPU "uncore" I/O (GDDR5 ctrl?), 2 phases shared for both GPUs. (vddci phase 1 or 2)
4 - 1× Volterra VT232WF feeds the GDDR5 chips their VDD or VDDQ (no way to tell which just by looking).
5 - 1× Volterra VT232WF feeds the GDDR5 chips their VDD or VDDQ (no way to tell which just by looking).
6 - 2× Infineon n-channel MOSFETs (042N03LS + 119N03S) located on the bottom edge of the PCB, for the PLX bridge chip.
7 - 1× AOSMD (AO)Z1024DI low-power integrated buck regulator

Groups 6 & 7 don't report data to monitor temperatures, but these overheating could still cause the card to throttle.

Hang on, what? so the VRM's are covered or not with the EK 5970 block Because I just ordered one of these from Eddy yesterday. Hope it does the job and keeps not only the cores cool but more importantly the VRM's.

The above pic shows 1.3v with 1000MHz core and VRM temps around 90C so am I correct in thinking at those volts and speeds that the VRM's are indeed cooled to some degree with the EK block?

The two "major" vrm groups seem to have full contact with the block. The smaller ones however doesnt seem to make any contact at all..?

[Onoff312]

Jesus that is pretty darn hot for a watercooled card to have those temps on the VRMS.

Quite high yea, but remember that its overclocked values, so still a fair bit better than stock cooler.
Would also be interesting to know what vrm is what in the gpuz screen..

[Razrback16]

Still haven't decided what route I'm going with the 5000 series...watching this thread closely for VRM cooling data.

[EvilClocker]

The result Jaredpace post on the other waterblock are mine.. Thats on a Dangerden block that didnt Have water going over the VRM, They just designed a new one. and I will have it this week..

What I can tell you is. The VRM are not holding me back tho.. and I only using 1/4 Tubing also.. when I get my new block with water over the VRM I post some more result.. so far my card is stable at 1000mhz/1250 Ram 1.3vcore VRM get to 80c

[Koolance]

koolance tim?

if you don't mind please enable your pm box

thanks

Whoops, it's enabled now! Like Eddy, I also find email easier to keep track of. If you send an email through our website, select "Product Question / Comment" in the request. We're training new ppl in the other departments right now and they may be a bit slower to reply.

??? Here is an overlay of our block over the HD 5970. GPU's look fine to me-- the fins aren't based on the center point, but extend well past them:



Also pics of the final prototype:

[Eddy_EK]

Nice, I guess it was just optical illusion.

[gabe]

Any ETA on when the block are going to start showing up ? My Card will be here tommorow.


Gabe Do you have plans to have one out this year?

I am delighted to confirm that the Epsilon 5900 is now in production.





Housing is thick clear polycarbonate
Base plate is chrome plated C110 electrolytic copper; cooling engine is dual 0.6mm pin matrix
Back plate is thick black-anodized brushed aluminum


As usual the product features pre-installed thermal pads, stainless steel standoffs, and re-uses ATI's excellent spring cross brackets. All AMD-specified critical components including ASICS, PLX, Memory modules (front & back), and VR's are cooled. As with the Komodo series, spacing between inlet and outlet G1/4 ports is sufficient to accomodate large compression fittings, but remains relatively narrow to allow clean and compact tube routing.

Price has not been established at this time.
ETA is 3 weeks.

[Mekrel]

for Swiftech and Koolance blocks.

I don't like the appearance of Koolance blocks though, chrome isn't really my thing and I think it looks tacky but the block looks well designed.

I personally like blocks with standoffs - I refuse to buy any full cover block without standoffs.

Standoffs = good contact without very small chance of shorting = good design.

No standoffs = Chance of bad contact if you over torque a certain section, can lead to shorting and you don't get any performance benefits out of it = bad design.

I'll leave it at that

Looks like of all the blocks, the EK is the only one with active flow over all 9 of the main VRMs....most notably over the 3 VRMs for GPU1.

Not sure how much it matters though...the 5970s still haven't shown where the clocking bottleneck is when watercooling.

EDIT: the Aquacomputer one gets the 3 over GPU1, but seems to miss the 6 closest to the power connectors (which I think are: 3 for GPU2, 2 for RAM, 1 for PLX--really hard to tell, there's a distinct lack of symmetry in the PWM design for this card).

thanks...it takes awhile to study all of these blocks

ek_eddy

will there be a budget version coming out?

Im hoping EK can make their bock fit properly this time I would not want to have to use washers.

[ReignsOfPower]

I would like all waterblocks to come with a custom back-plate too. The stock back-plate exceeds the PCB and adds unnecessary length to the card (that being said, it shouldnt lie short of the PCB either). It also looks fairly ugly.
From an aesthetic point of view, Koolance blocks look to mean the business, but as stated in this thread
http://www.xtremesystems.org/forums/...12#post4135412 by DD, they are working on a revision which runs water over the VRMs purposefully. I'm putting my money on DD being a top performer once again, just like the 4870x2 waterblocks that preceded it.
