The 5800 series aftermarket cooling thread.

[The Sauce]

I have a HAF922 with two 20cm intake fans, one 20cm top outflow and one 12cm rear outflow. This case has major airflow. Also I lapped the t-rad to make sure I had perfect contact and reapplied Arctic 5 paste 5 times in different patterns to ensure optimal coverage.

It got the college try.

Are you sure you seated it right? I have the TRad on my Sapphire 5870 overclocked to 875 and it never goes over 60C (10min of furmark). I stop it after 10min bc my VRMs hit 100C. Ive also push the card over 900 core (forgot what volts...>1.2) and temps never got above 65. Ive been really satisfied with the TRad.

Edit: Nvermind...read it as 860 instead of 960...haha. You must have gotten a really good stock cooler b/c my stock ran really hot. The TRad was a big improvement over it.

i'll second that first bit. i finally got the t-rad and vrm-r3 set up, and i've never seen my core or vddc phase temps above 60 in any application, furmark or otherwise. you might want to try reseating it..

 

[poohbear]

meh, just went ahead and bought the Sapphire Toxic video card. For the extra $20 it saved me the headache of finding an aftermarket cooler that fit & the installation. It's just as quiet as my 8800gt w/ accelero s (almost passive). Especially since aftermarket coolers go for so much more than $20 these days.

Huh...Maybe the 5800's run hotter? Smaller die size? I tried reseating it about 5 times - even lapped it. Tightened the holy hell out of the thumb screws. Not sure what else I could do. I've put plenty of heatsinks on before and never had any trouble like that.

the time has finally come to revisit this thread, having ordered my xfx 5850 xxx

I think I have heard people getting better results by attaching a single 120mm fan to an accelero S1 rev 2 rather than a twin turbo, wonder how tricky tieing the fan down would be?

Shoulda have picked up a S1 when it was on sale at SVC.. gotta shop around now

EDIT: S1 would need vrm sinks on top of that.. might as well just get a twin turbo pro then. what would be the best place to get one now? $53.20 shipped from SVC, $56.56 from coolerguys. Where did you get yours from? oh wait, $45.70 from ewiz sounds even better... $41.12 after BCB from ebay, but we are really pinching pennies here

no surprises there, S1 rev2 is a bit bigger than twin turbo. I wonder if the stock heatplate could be reused as in the case of twin turbo? Presumably so, since twin turbo is basically a downsized S1 with 92mm fan shroud

here are some pics of someone using S1 on his 5850 (without the heatplate though it seems)
http://www.overclockers.com/forums/showthread.php?t=620194&page=2

Assuming S1 rev2 can indeed be used in tandem with the stock heatplate, I wonder if S1 + something like gentle typhoon would work better. Price difference is quite negligible, and TT Pro will definitely more elegant (zipties hanging inside the case is never a pretty sight...). the 120mm fan would have way more air moved, but wouldn't cover the entire card perfectly. I am especially concerned about covering enough of that heatplate. Guess you never know until you try it.

 

[bradyapba]

TTPro has 2 - 92mm mans. Cover the whole card, whole stock plate, and blows right onto where the vrms are, and we know it works with the stock plate, and its a little cheaper. Win Win.

 

[konakona]

yeah, thats where I was getting at, those 92mm cover the entire region.
but the heatsink itself is bigger with the S1, and while those arctic cooling fans might be decent in their own light, I doubt they could match the legendary gentle typhoons.

does $41.12 shipped after BCB sound about right for TT Pro though?

 

[bradyapba]

Yup thats about right in price. I paid $47 shipped, with no BCB.

Pictures are nice
good thread

After a couple of days with a new rig with a 5870 standard cooling, I get practically no noise with the fan....even with extended gaming. The most I've pushed it is 54c and fan auto running at 2200 rpm. Not noticeable. Using a lian li case with has lots of space inside and good cooling....I think alot of the reported heat issues deal with cramped cases with the card not having enough breathing room.

I think it mainly has to do with overclocking the card. I take it you are running your card at 960/1300 like The Sauce is? I intend to do some heavy oc'ing, and hence third party cooling should come in handy. The rest of my system is very quiet and I know I can't live with a turbine, even if its just during the gaming sessions.

I'm looking to cool my 5870 and I was starting to look at Accelero Twin Turbo, but then noticed that there is a "Accelero XTREME 5870" in Arctic's website. I read that this will be available in April. Seems interesting. I was also looking at a universal GPU cooler from coolIT OMNI ALC.

BTW, What software to use to check GPU temp including VRM temp ?

not oc'ed i take it. If getting a heavy OC, temps go up, fan speed goes up, jet engine insues. At stock they are fine coolers, very quiet.

gpu-z.

 

[Hadsus]

Actually I got my card up to 68C.....the temp jumps down fast when you exit the game....fan still at a very low level. And, right, no OCing yet. Really not a need to except I suppose with a handful of games out there.

 

[Spike99]

gpu-z.

I downloaded GPU-Z. I see the following temps descriptions:
GPU Temperature, GPU Temp #1-#3, VDDC Phase #1-#4 Temperature & VDDCI Phase #1 Temp

Which one of these is VRM temp ?

 

[bradyapba]

all 4 of them are. YOu have 4 vrm chips on the 5870.

 

[Kenmitch]

So anybody found any links to water block reviews for the 5850's? Or anybody got some rec's for a good one. Just started looking at them as stock speed the stock cooler is more than enough with good airflow in the case.

I'm sitting at 950 core and 1300 memory so far. Temps in the 70's(all) during furmark testing with fan at 50% which is too noisey for me.

I'm using the Asus modded bios which I modded to boot at what's in my sig. Gonna redo it again and increase my sliders and bump the voltage up to 1.200 on the core as I was getting some artifacts at 975 core at that voltage. I figure I'd rather set it at boot to the overclocked speed than have to play with Afterburner.

Thanks,
Ken

OK... Thanks for the info.

 

[The Sauce]

EUREKA! I took apart my card again. I removed the TIM from the R4 and applied AS5 directly to the VRMs. I also re-lapped the t-Rad2 and reapplied AS5 to that.

Presently running Heaven 1000/1250 @ 1.175v. GPU temp 55C, VDDC temps ~ 50C. Bingo! Furmark still gets it hotter but VRMs are still around mid 70s whereas before they were hitting >100C.

If you buy an R-4 VRM cooler, ditch the TIM and use paste. It seems that is the key to overclocking these things - keep the VRMs cool.

 

[Headfoot]

sexy oc dude, glad to hear it worked out

 

[konakona]

That's actually faster than 5870s eh? Those extra shaders on 5870s do not get used in reality IIRC, so the 5850 and 5870 are very close clock for clock rigth?

 

[The Sauce]

Not sure about real-world gaming but the last time I benchmarked it at about 940/1300 with 3DMark Vantage it was pretty darn close to a stock 5870. Vantage probably leverages those extra shaders, though.
