After market cooler for the ATI 5850

nice job Sgt.McRuff

[trt740]

trt740 use amd gpu clock tool to monitor vrm temps. With furmark mine are getting to around 48c-51c at 1.175v 970c / 1300mem
Wish I got the temperatures for vrms with stock cooling.

stock plate

in case no side fan

in case side 120mm fan

Sorry for crappy iphone pics.

try it with this tool http://www.ocbase.com/perestroika_en/index.php?Download and tell me your temps

and which sensors are they in amd gpu tool

HIGH 60's. (room temp 76f)
also new gpu-z out 3.6 that tells vrm temps

on air mines in the 80's under max load using occt which stress my system more than furmark, but we are talking air against water cooling. I wonder what it would be with the stock air cooler wish I would have thought to check. I wonder what acceptable.

[Sgt.McRuff]

Well my vrms are air and that is in high 60's. My core is only around 39-40c. (occt)
I have my vrms, in exact same setup as my 4890 and there about 12c cooler then 4890, which is good.

vf1000 fits w/o modding

this thread made me buy a 5850.. i can watercool it with stock plate =D

[mattlef]

This looks like great for us. Hopefully though, we'll see a bunch of coolers come out for the 5850, so we don't have to use the stock plate.
I wonder if that new xigmatek is gonna ship 5series ready, or if Thermalright is working on a cooling option as well.

Hey pal wont u mention about your marine choking on a peanut card?

Hey pal wont u mention about your marine choking on a peanut card?

I would but it was with the stock cooler on the card during stock testing and isn't relevant to this topic. MY 5850 died during testing using the stock cooler and stock voltage using occts gpu test . I was going to show a comparison of the two but the results seem to speak for them selves.

run occt and tell us the vrm temps.

Yes they are but since water haul all the heat away and leaves none in the case and doesn't let the pcb radiate heat there is a difference. Plus my cooler cost 29.00 and your well is well over double. I do like the heat pipe over the voltage regulator I may give that stock cooler mod a try and put enzotech heat sinks on it. I'm not sure it will work on a 5870 but we will see. okay now I see the stock plate mod won't work on the 5870, different cooler all together.

[mattlef]

That heatsink looks fantastic..... I might just end up copying you :P

[Theorw]

Yes indeed itys a very beautiful combination!

[deaffob]

I just installed Accelero Twin Turbo on my 5870 with some extra heatsinks on Fase Ram. But my temps shoot up to 75 on gpu and average vddc phases hit 110 after heavy furmark.

You need to turn the fan up to 100 percent, something is wrong there and make sure your not using amd gpu tool it disables the fan speed.

[zfactor]

the gfxchilla works also. fits great on the 5870 ill try to get some pics i got to get the camera back from the wife's sister arghhhh. im seeing 37-39 idle and furmark just a hair over 70.. not to bad imo

[mattlef]

Has anyone tried one of the Thermalright offerings?

[deaffob]

@trt740 I thought if I connect the Twin Turbo with 12v it is always 100% and I can't control the speed? Anyway I turned up to 100% and it's the same maybe it's because I live in California.

might be case flow take the side off and try

Thanks for sharing this! 1 question: Did you only have to use the 4 VRM heatsinks I see in your pic? Or are there more places to be heatsinked when using the VF1000?

Also, temps would be nice to hear

[Locke]

Does this look okay for temps and overclock on the 5850?
The GPU 2 temp seems a bit high.

thanks!

First post here

The scythe musachi is fully compatible with the HD5850.

But i wanted to keep the black plate for a beter cooling of the VRMs, so i modded the mussahi

Here is the pics :






The result (musachi fanmate at 1/2 = silent) -->
(stability test, post-processing, 1920*1200, msaa 8x,xtrem burning mode)

idle after bench (fanmate at 1/4 = very silent) : 34°


édit : more pics here link

i have everything in a Antec Mini p180 now, w/ 1.2 vgpu via afterburner @ 900 core, 5850 loads in the middle 50*'s (c) while playing COD series (4 and 5)

i might be the drivers i'm using, but GPUz is acting up. i'm still looking for a fix on that. i added the sinks to the heatpipe on the digital PWMs for looks, i'm sure they help, but i think they look better then that ugly heatpipe that was on there.

/edit. i also have the vf1000 plugged into the case 1 fan header on my motherboard, fan profile set to silent. every once in a while it will ramp up in speed, but i don't know if hats from CPU load or GPU.
