For the past many months I've been running GPUGRID with my modest GSO 9600 and BOINC 6.5.0 on my Dell Pentium D 3.2.

Recently, perhaps twice a week, I've been getting BSODs caused by Nvidia code. I have a cheapo extractor fan sitting in a PCI slot. My GPU runs typically at 85C-87C, with one peak into the 90s.

I turned off GPUGRID a couple hours ago and the GPU has settled at 68C.

Should I quit running GPUGRID for fear of frying the card, or is there something I missed?

Thanks, Tom

No, you're pretty spon-on, you are frying the card. I'd recommend some better cooling if you want to continue crunching or downclock the card. Regards, H

if your dell computer has a grill in the back, may i suggest

case Fan- size to be determined by how much screen mesh you have..

no need for holes, you zip ties...

i post pic for you, it'll cost like no more than 5 dollars...

http://img199.imageshack.us/i/1003545f.jpg/ thats a 9400 gt pcie sitting in the picture...

my gpu runs no hotter than 76 C... that 80 mm fan helps remove the hot air as the only case fan is the one for the cpu and i added this case fan to help...

go to newegg, find a cheap fan with no shipping....

that fan in pic is only 3 inches.but it works....

also, if the gpu has a fan and is not pci, get evga or rivatuner that fan to 75% or more..

my gtx 260 standard fan speed was 40% and it kept crashing too but i added evga precision and now under gpugrid, it runs 58-63 C.

My GPU runs typically at 85C-87C, with one peak into the 90s.

Another additional fan that might help is a drive bay fan in an empty slot. Antec used to make a nice 3-fan unit that had good airflow. In a tower, put it in the top drive bay slot to pull in cool air where the case is hottest.

i doubt that his dell computer would have an empty drive bay as it's a p4 which means it probably has a floppy drive and 1 cd or 2 cd drives as i have one just like his...
but in case he does; you(scott) mean something like this

when is gpugrid going to update the back-end software where we get buttons for stuff??

Thank you all for your contributions.

• The BSODs certainly were Nvidia caused. I did not write down the details but the offending program was NV4_something, and the cause in each case was an infinite loop.
  
• I like the idea of more case cooling so I bought a fan to fix on the back of the PC, close to the graphic card. Should be here Wednesday.
  
• The hard drive cooler would not work in my case. The two hard drives are fitted well away from the CD slots, in their own plastic holders.
  

Being a little more specific, I was running my XFX GSO 9600 at factory clocking, and 70% fan speed. 70% was just acceptable, noise wise. I also run rosetta@home 24/7.

Since I switched off GPUGRID I lowered the fan speed to 50%. The GPU temperature is now a constant 70C. Let’s hope the new fan will let me get back to GPUGRID-ing!
