Which manufacturer is going to be ready with 5850/5870 blocks?

[Eddy_EK]

Hi!
This is something that is definitely not ok.
The Temperature between idle and load should be mush smaller.
I'd suggest you send us picture of the contact to our support e-mail so we can sheck it.

Also, what is your watercooling setup?

[Mazlov]

Those temps look off idd. I tested my EK-FC5870 @ stock speeds yesterday night, and the results were 21C Idle, 31C load on the GPU. VRMs were about 50C.
I'd expect 5850 temps to be a tiny bit lower, and as far as I can judge, the blocks for the 5850 and 5870 share the same design principles.

I have a big water circuit (FSB->RAM->VGA->CPU->FET->NB) with a very big but passive radiator, so my water is lukewarm but not hot (I could take a bath in it after 1 hour gaming, but it wont boil under any stress test...). This radiator could cool my previous system (everything was the same [CPU, motherboard, ect.] and my VGA was a 4870x2 with an XSPC Razor block). The room temperature is ~28-30 C˙, so I think that 40 C˙for the GPU is not a big number when it operates with a passive radiator.
The VRM temperature (100+) is the problem, this GPU temperature (40-50) would be fine for me (it was ~90 with stock cooler, 60 is not a problem).

Try to put stock cooler back on check temps. And send picture of the block contact to us with stock cooler temps.
Then we'll see what could be the problem. Also water temp under 30min load would be interested to know as bigwater does not convince me at all.

I hope EK 5870 block is the best on market Because it has been just shipped to my hands but i still don`t have 5870 VGA

[janos666]

Here are the pictures (sorry, but I do not have a camera, I took these with my smartphone and without proper lights...):
I made a change: I used the thermal pad from stock cooler (RAM plate) to cover the hole (over the VRM) on the block (and I removed the gray pads from the three affected chips on the PCD -> big white and two middle ones) and I used doble layer of grey pads over FETs.
I mounted the block with standoffs and results are as bad as they were last time when I used standoffs. But the back of the PCB is not as hot under the white VRM chip as it was before. I will try to use the stock cooler's thermal pads for the FETs too.
Is it possible that the equipped thermal pads can not transfer the heath well enough? The good contact is proved by the permanent deformations and my GPU temperature is not too high (~32 C˙with cold startup which is near to the ambient temperature and good enough for me under load with a passive radiator) but my FETs will die.
I think that I will kill my card with the numberless block remounts. (And I will waste a complete tube of MX2 compound as a tip. )

[janos666]

I replaced the equipped thermal pads with the stock cooler's white snot and VDDC Temperatures are acceptable but far from good (~63 C˙ at stock clock under load). The GPU and the whole PCB where covered by the block are cold. When we reach the VRM area the PCB is lukewarm and it is very hot after the block ends (and stay hot until the end of the PCB).
May be it will work until Geforce-Fermi arrives and I can put this thing to the trash. (Oh, I even more: will SELL it to a looser like me. )

[Eddy_EK]

The contact looks good.
It can be seen that you dont use standoffs as the pads are very much squeezed.
I hope you checked the card is not bent too much.

I would still express the doubt about the bigwater cooling capabilities to cool your whole system... And blame bad temps on it.

[Jamesrt2004]

lol complaining about temps using a passive rad.

[janos666]

My water temperature after ~4 hour average usage (which ended with some Furmark + Prime95 before the measure) was 38 C˙Yes, it could be less if I switch off the central heating in the room (the room temperature is 25+ C˙). But this is not a steam machine! God! I am complaining about 100+ C˙temperatures (not that my GPU temperatures are not equivalent with the room temperature)!
But again:
- This radiator+pump (very big one + 1100 l/s) was enough for this system before I replaced my HD4870x2 with this HD5850. Which card can generate more heath? (Assume it as a draw and we were discreet.)
- My GPU temperature is always OK. (under 50 C˙at ANY situation, even with overclocked card under Furmark load -> it is 31 C˙right now at idle - with cold water and it is under 40 C˙after some furmark at stock frequencies.)
- I used the standoffs (and the equipped thermal pads) at the first time (I did everything step-by-step as the enclosed manual said) and I had up to 120 C˙VDDC temperatures (all the 3 sensors showed this).
After I dismounted the block at the first time I could see the edge of every chips on every thermal pads.
- I remounted the block without the standoffs and VDDC temperatures were under 100. (Nice surprise.)
But it was still too high and my PCB was malformed. So I had to do something...
- I remounted the block with standoffs but I used the equipped thermal pads in double layers over FETs. The VDDC temperatures was under 70 C˙, I thought that we will finally arrive to our destiny but the card was unstable. Maybe the gross FET covers held some other pads to far from other chips... So, I had to dismount the block again.
- I replaced the equipped thermal pads with ones from stock cooler and now it seem to be acceptable.
Idle temp are: GPU - 31 C˙VDDC ~32 C˙ Load (furmark, stock frequencies) temps are: GPU - 38 C˙VDDC ~56 C˙

Every time I did something with thermal pads (or with the pressure over them) over the VRM area there was a significant change in the VDDC temperatures (it did not affected the GPU temperature). Can you explain it with the other parts of my cooling system? NO.
The difference between the first and the last (up to now) state is 120-56= 64 C˙. But, delta values: GPU 38-31=7, VDDC 56-38=18. This is not far from acceptable. Should I take my cooling system to the trash? No. Should I do something with the thermal conductivity over the VRM area? Yes.

The card is stable now and temperatures are acceptable (with a passive radiator). But I have to get some fresh (and good) thermal pads for FETs if I would overclock the card because the end of the PCB is still hot (and this heath should came from the VRM area).

lol complaining about temps using a passive rad.

My problem is the high VRM temperatures. More specifically: the difference between the GPU and the VDDC temperatures under furmark load. If the GPU temperature is low enough then VRM temperatures should be acceptable too. If the difference between those values is low during normal operation, then it should be low during any water temperature.
For example: If the normal state on an active system is GPU 25 VRM 32 and I have a hot water then I should be (for example) 40 and ~47 and not 40 and ~120 (and not even ~80).
Can you see the problem?

I would still express the doubt about the bigwater cooling capabilities to cool your whole system... And blame bad temps on it.

My CPU temp is OK, my GPU temp is OK. How can other parts of the cooling system affect only my VRM temperatures to be so bad? Are you serious? The water in my cooling system can cool a Q6600 (1.45V), an x48 motherboard, an RV870 chip, but when the water is flowing over the my VGA's VRM area it would singing: "Ha-ha... I am too hot, I will skip to cooling FETs. Ha-ha." Or what? I can not understand.
The problem shoul be the thermal conductivity between the heat sources in the VRM area and the copper block. This is proved by other facts like VDDC temperatures always changed (in a large scale) when I made some changes with the termal pads overe the VRM area. And my whole PCB is cool expect it is hot over the VRM area (it is cool over the GPU).

hey eddy, when we see the waterblocks for the HD5770 on your site. today is the 23rd

[pici]

hello there!
Hey i have been waiting to leave a comment here.I wanted to see what eddy and gabe think...In fact i know plp that would buy this so there would be market...Well i got unlucky with gigabyte 4850 cf setup when a year after wanted to water it.No block out there compatible with it , that would water the ram also.Ram gets max 96 c.
In the future a plan to invest to 5870 so i was lookin at its layout and could help notice the similarities....

I know the mosfet part may not fit but if there is a block for the ram,gpu only?Where maybe u could just unscrew the mosfet part?

[aspms*]

Is there any difference between EK-FC5850 and FC5870 blocks or it's just a name difference on them to match GPU you are using?

has anyone seen HEATKILLER® GPU-X³ 58x0 internals?

[Eddy_EK]

Latest addition. Backplate for 5850/5870 cards.
Backplates also support cooling of back RAMs when/if the will be added by manufacturers.

[Garrett]

Awesome!!!!
Looks very good and also helps to prevent bending of the card
Any word on your price yet, Eddy?

[Moto450]

Looks nice.

[Sadasius]

Eddy you rock! Those look awesome!

[Silverhawk]

What should VDDC temps look like using the EK5850 block? While running furmark, my VDDC temps are around 68-70C, while GPU temps were at 31C idle and 39C at 99% load.

Depends on the Vreg Voltage. 70°C are good, looking at the fact they can get over 100 with stock cooling...

[Baulten]

My GPU temps are around 30C (39C full load with 1.35 volts; was curious about temps), and my VDDCs get around 40C. But my VDDCl gets to 60-70C full load. So, not sure how representative my temps are.

Did more testing today, and VDDC temps didn't break 50

[WaterFlex]

Wow! That backplatez are awesome!

[dingdong555]

Eddy, IMO they don't look good.

Any possibility to make it the size of the WHOLE card? I know it's kinda pointless but it'll look MUCH better.

imo they look good....

but need to go the whole length of the card.. would make it like WOWWWWWWW

[Sil2]

Thats what dingdong was trying to say, it would look a whole lot better if it was the entire card length.

I agree too.
