First time poster here, hopefully i can get some help from you guys if possible... any tips or advice would be much appreciated
i have a few questions and problems with my GPU it seems like... I just downloaded a few games the other night (The Sims 3 and GTA IV) and both games run for about 15-20min straight and then my computer shuts down completely without any warning... this never happened to any of the other games i play (Call of Duty Modern Warfare2, NFS Shift and Prostreet) and i run some of those games on high res with the graphics near max quality...
ive downloaded RivaTuner and tried to adjust the fan speed and set it to 100% cycle duty... however i come across to things... 1. doesnt matter if i set it to 25% or 100% i cant hear any audible difference in fan noise, and i have the casing off on my computer.. i thought maybe with it off i could hear the change in fan speed but i cant... and 2. after i set it to 100% cycle duty it'll stay at that speed while my GPU idles at around 55c-56c... but as soon as i play The Sims or GTA IV the fan speed automatically adjusts itself anywhere from 30% to 70%... while my GPU temp keeps rising... i can set it to 100% and it will automatically lower itself... it seems to reach 91c+ before my comp justs down
also i cant seem to get Rivatuner to display my GPU's fan RPM... i went into Plug-ins and check marked it and it still doesnt show me the line graph... i can get the other misc. graphs to show, but not my GPU's fan speed...
any advice? i know theres alot to read but if anyone could help me out, that would be great... thanks in advanced
ive tried two different drivers and the same thing seems to be happening with both drivers.... PC shuts down within 20min of gaming because temps reach past 91c+ and the fan cycle duty is randomly somewhere between 30% and 70%... the only way i can play those specific games past 20min is if i Tab-Alt out of the game and wait for the temp. to drop back down to 61c
im currently on Forceware 196.34... i also tried 196.21...
as for the fan rpm monitoring, i think i found out my GPU doesnt have a sensor to monitor it, so i guess theres no way to see if my fan's actaully working, or if its stuck on one speed
i forgot to mention if this helps at all..
E5300 @ 2.60Ghz (Stock)
3Gb of Ram
XFX 8600GT GPU
is there anyway to lock the cycle duty % down so that it can run @ 100% all the time?
or is it possible my GPU might be defective?
ive already cleaned all the fans out and got rid of as much dust as possible but that didnt seem to help... im currently running the CPU with the side case off hoping that would help with bring the temp down at the very least, but that was unsuccessful as well
i dont believe there was a fan control dial on nvidia control panel, i was looking around for awhile but didnt find any adjustment sliders for the fan, thats when i turned to Rivatuner
ive opened a ticket to XFX in hopes they can repair or replace my card... i just wish that i was 100% certain my fan is no good.... i since my card doesnt seem to have a sensor to record the RPM of the fan
yeah i bought the card on tigerdirect.com
and i do think the card is starting to die on me... i just ran one of my old games like NFS Prostreet, which i never had a problem with, but it ended up shutting down on me like 10-15min into the game again...
its strange because i did a stability test with Furmark and i got the GPU to hit 107c on the stress test and it didnt shut down... but for some odd reason when i play gta iv, sims3 and prostreet my computer ends up shutting down on me with no warning... unfortunatly i cant see what temp the GPU is at before it shuts down since its always completely random
well i always used the one that came on the ubuntu discs. any program should work though. if you have a big internet connection i reccomend the ubuntu one because you just run the disc, and from there you choose test ram and it does it for you.
Those older entry/mid level Nvidia cards had tiny GPU fans that easily pack up with dust and die. No fan = High heat = burnt out GPU. Can you visually confirm that the fan is turning by taking the side of the case off and looking at it while the computer is running? Even at 2D idle, the fan should be turning if it is working.
Burnt out GPUs tend to fail and crash at much lower temp thresholds than fully functional GPUs. Having it fail at lower temps now might only mean, that at some point in the past while not being monitored, heat climbed to a damaging level. I have personally witnessed this with at least 3 8600GTs (and 1 8500gt) in friends computers.
Pointing a fan straight at the GPU in a closed case, only works IF you have a surplus of exhaust pressure. Otherwise it just moves warm air around inside the case, warming up the rest of the internals. Having a side mount fan pull air AWAY from the GPU is without fail, a good way to drop GPU temps, regardless of the total fan setup.
yeah i can visually and physically feel the fan running at all times.... i can put my ear right next to the fan and set the fan speed at 25% or 100% and their is no difference of fan noise.. it seems like the fan is stuck on one speed reguardless of the GPU's temp...
i also can seem to get the fan to stay at a certain percentage, even if i control it manually... i made a fan profile of 100% cycle duty and set it up to launch whenever the temperature ranges from 55c to 999c which should mean it should be forced to run at full speed at all times... however it ignores the command and i can see that the fan speed would automatically jump around
