GPU temperature Issues

I just popped a 9600GT into the center PCI-E x16 slot between both of my 8800GT cards yesterday and got it all configured for folding. When I opened speedfan today, the temp on my top 8800GT was reading 112C :eek: The 9600 was blocking the Zalman VF900 from getting any fresh air. I underclocked the card a bit and added a ghetto fan array and removed the case side. Do you guys have any tips on getting my temperatures more under control? Its holding at right around 98-100C. For comparison, the Bottom card is at 84C. The fan speed is maxed on the VF900s.

Pic of my ghetto fans.


 
Holy melting gpus batman!

That's pretty hot, my 9800gx2 only gets to 80c while folding.

I don't know that is would help, but have you tried having the fans pull air instead of pushing?

Nah, I doubt that would help. The way it is now, the fans are supplying the cards with a steady stream of cool air, which is what they need.

Just tried that. GPU stayed the same temp. I paused the client and its still at 93C. Blowing cooler air in did a lot more.

Just plugged the tri cool on high back in blowing on the cooler and its already down below 80C idle.

Update: I added a second high flow fan blowing from the other side, and now the GPU is at 89C under load. I think I'm going to either get liquid cooling or see if coolermaster is selling those 230mm fans so I can mod my old sidepanel to fit one.
 
your best option is blowing at the heatsink.. so even though the heatsink fan isnt doing squat.. the side fans doing all the work.. doing that with my 8800GT right now to keep it under 50C at full load.. have a tri-cool fan set on high, blowing air directly at my duorb cooler..

if the side of your case doesnt have a spot for a fan.. another thing you could try doing even though its total ghetto rig.. find a piece of cardboard the size of the side panel you have.. cut it to fit and cut an opening for the fan.. then mount the fan on the piece of card board.. just make sure its thick enough to hold the weight of the fan.. its ghetto but it will work.. it will keep the correct pressure in the case.. and keep the fan from recycling hot air back into the case..
 
My side panel did have a fan blowing on the cards, I just don't think it was supplying enough air. I've got it under control now. I can live with 91C. If it dies, I've got a warranty, and yes, I registered the card. :D


 
Meh Wimps that aint hot, its been 45c to 50c outside at least that is around the 110 to 120f odd ;)
And yes I do fold
 
and thats specifically why i dont live in Australia and will never visit Australia during the summer there :p

Build a new computer and put said 9600GT in it? :D

Off hand, have you tried forcing the fans to higher speeds in RivaTuner or something similar?

I live 100 mi from Death Valley, so those are the temps outside here in the summer. :eek: :p
 
Excuse this rather noobish question. :rolleyes: I was of the understanding it was the shader stream count in nVIDIA cards that had the most effect on the F@H GPU2 clients PpD. :confused: I was also under the impression that it was not a good idea to mix and match different capability GPUs and different shader stream counts in the same box for optimum F@H GPU2 folding. :( From what I understand the PpD will result in being suppressed to the lowest producing card :( Does any of this ring true to the "masters of the Universe" guru folders of the mighty [H]orde team 33 :cool:

With all the above semi technical geek talk over I went to the good ole' Google search URL and found that the 9600GT has 64 shader streams and the 8800GT has 112 shader streams. The pernt (pun intended :p) I was tryng to make is if there is the slightest chance of screwing up a 8800GT over some 9600GT it doesnt make any sense to me. (just beg, borrow, steal or buy another boxen to run the 9600GT in :rolleyes:)

I have no ideer what a 9600GT gets PpD wise, but having a Q6600 boxen with a "fire breathing" PNY 8800GT GPU in it (which is only a UPS delivery away from WC'ing :p) I'm pretty familiar with the 8800GT's PpD amount. I just up the shaders to 1782 and ATM cool it with the Accerlero HS (with a undervolted 120mm fan) and let her rip at about 50c core temp with a 22c ambient temp while happily crunching GPU2 on core #3 and WCGing on cores #0, #1, and #2. On the long winded 511 pernters it only gets about 3500 PpD, but I've seen it go as high as 5000+ Ppd with the little 353 WUs :D What's the high point in PpD for a 9600GT ? :confused:

These are only my humble observations and opinions ;) (my $0.02 cents worth, as it were :rolleyes:) I'm sure there're much more knowledgeable GPU2 folders on this terrific folding team (team 33) that'll straighten out any misconceptions I might have . :)

Have you checked your fan on the card. it seems like it's failing. make sure it's spinning good and hard.

Yup, the fans are maxed. I have a Zalman VF900 which is attached to my ancient thermaltake fan controller and the knob is all of the way up.

Yeah, I've read the same things, but both 8800GT cards are doing ~3000ppd on the big 511 point WUs and when they catch a small one, it jumps to 4500 or so. Maybe the new 181 drivers don't care as much about mixed shader counts.

Yup, the fan is maxed. I might try mounting a super high CFM fan in my side panel to see if that will do it, because right now, it sounds like a jet engine behind my monitor.

UPDATE: I put a 60cfm fan in my side panel, which is directly over the video cards and now its staying under 85C. I guess my stock CM side panel fan wasn't pushing enough air to be effective.

Aint Death Valley a desert tho, Our desert temps are like another 10c odd on top.
I am not in a desert area tho its heading towards that part of the country. :)
The recent heat wave equaled the number of days @40c plus and forced the local wildlife into desperate measures to find water and a record number of trees just shedding limbs.

At least the fbox and my main machine didnt shut down, both have High CFM fans aimed at the Video card's:D:D:cool:
 
Yes it's desert country. Dry heat vs. same temps range but 80% humidity as in Yuma AZ when I was stationed there. :cool:

I no likie the cold except for where it helps folding. :p
 
maybe use something to push the cards a little bit away from each other. No enough to break anything but it might give the fans a little bit more air to draw in
 
i was going to say something like that earlier.. but that might be a pain in the butt with the heatsink on the top card.. it doesnt give you to much room to separate them..
