After market cooler for the ATI 5850

[SonDa5]

The stock cooler does a decent job but I'm sure other cooling methods that are superior can be done.

This is HD5850 at 1000/1200 100% load on furmark doing some tuning.



Any after market cooling mod should show some good improvements from what the stock cooler can do.

Sorry but, stock fan at 100% , this is not "decent"

of course the stock fan is good, but when you O/C, it's very noisy

Just presented the numbers to see how the stock cooler works under load. The temps in my screen shot seem to be safe for o/c HD5850.
I agree the stock cooling is noisy.

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

thanks!

Either cooler is not making correct contact. Or the temp sensor isn't any good.

the waterblock prob isnt making good contact, if i tighten the block down too much the card warps and the MB doesnt post video.

thanks for the thought! I'm gonna mess with ti more when I get my i5 win 7 build up in a few weeks.

Here is stock cooling temps with fan cranked up 100% when idling no load. I think this will be hard to beat for standard heat sink and air cooling.

So, you don’t mind that it sound like a Saturn V in your case/tech station?

It is loud but it does a good job of cooling.

I would much rather have quieter cooler but it has to do a better job at cooling as well.

Hi guys, I would like to know your opinion on how to cool OC asus 5850.
Im getting 5850 on january didnt preorder it coz i thought there would be relatively enough of this cards...mistakeeee
well I narrowed my choice of cooling from thermaltake ISGC v320 and accelero S1 rev 2 to accelero after I saw it can be fitted on card with some tweaking.
Im planning to OC to max (accelero + 2x120 noctua [S12 1200 ULNA,FLX on ULNA])

Well I would like to know your opinion what cooling would be better
1. heatspreader on + heat sink (acceleros' or thermalright) on VRMA + accelero
2. heat sink (acceleros' or thermalright) on RAM + VRMA + accelero

? what will be most efficient?

really thanks

Water cooling is the way to go, much more efficient that air cooling.

Waiting my HD5850 and it thnin ill buy these : T-rad2 with a Vrm2





This is supposed to fit. And can be CFed

the t-rad² fits the card well, but not the vrm1 and vrm2 w/o modding



the gap between the two holes is 81.3mm, on the hd5850 it's 84mm

i hope you didnt reply on my question?

[Boulard83]

THX Karam !

Im not mattered by modding it

[Blkout]

i hope you didnt reply on my question?

Yes I did, and you're welcome. Free advice.

[hawktulu]

Yes I did, and you're welcome. Free advice.

im asking which is better - back plate on or just heat sink on RAM and VRMA and you answer me with water cooling..

if i want to know which is better air or water I WOULD ASK..

If I thought an air cooled solution were worth mentioning, I would have. Hence, the recommendation to go water. You're welcome.

I have just purchased 2 x 5850s and find them rather noisy so i want to stick some aftermarket coolers on to silence them. I have a few questions:

1)I have a VF1100 with the zalman heatsync pack on my old 8800GTX, would it be relatively simple to transfer it to one of my 5850s?

2)I presume once i fit the cooler the memory and other critical components will no longer be being cooled, what components are these and what should i do about it ?

3)Any other advice before i do this?

[boxrick]

No one have any advice?

boxrick : get an THERMALRIGHT T-Rad² ,get a big low rotation fan like an 120mm that spins at 1000 or even an 140 low-spinning fan like the new XIGMATEK XLF-F1453 and mount the fan on the cooler with some metal wire if its too big for the original clips,if you wanna play with it a bit you can even put 2x12mm on top .
its really easy done in 5 mins,i have a 14mm fan on my VGA cooler thats mounted with wire cause its too big for the original clips and besides it blows air directly to the RAM and VRMA so you dont have to worry about them.
if you stay up to 850mhz oc you can even lower the fan to 800rpm.
best thing is once you get a new gfx card in the future you just unmount this cooler and put it on the new.
...you just dont hear nothing from a good fan that spins at 800-1000rpm,completely silent.
i think i will never again use stock cooling on a gfx card.

[darckhart]

i thought the biggest problem was those stacked dvi connectors. gets in the way of the fins for most of these large heatsinks.

Ok guys i did the mod, stuck a zalman VF1000 copper GPU sync on my 5850. Idle temps now at 36 degrees load on 55-57 ( with fan on low )

This is miles quieter than the stock cooler no modding required simply do the following:

1) Pull off stock cooler / heatsync and removal thermal gunk from GPU.
2) Take apart the stock cooler so you simply have the baseplate.
3) Reapply the black metal baseplate to the card without the shroud and the rest of the rubbish
4) Put some fresh decent thermal gunk on the GPU and install the VF1000
5) Enjoy

Chinstrap @ in this picture what is the brand of vga cooler ?

VRM temps ?


I cannot find a decent cooler for 5850 (thinking in VRM temp)
