Hi,
I was having this problem where the fan speed keeps changing. At times it goes up to max speed and then drop back down. It's getting really annoying. The fan gets loud and then quiet. It's irritating. Initially, it occurred in Windows 8.1 Pro. I thought it was Windows 8.1 issue so I reverted back to Windows 7, which I prefer much more lol. However, the problem still occurs. Though my computer is awfully more quiet than Windows 8.1. I assume it was a fresh install, hence it's quieter?
Anyways. The problem still occurs. When I run some programs like Firefox and play some games, the fan goes loud for a few seconds. Sometimes just idling does that. The same for boot up (both Windows 7 and 8.1). I didn't know what the issue was during then. I thought it may be CPU. So I reapply the thermal paste and cleaned the fan a little bit. Not the issue. I was using HWMonitor all this time. Initially I saw the CPU RPM was fluctuating but that's not the case. I then saw it was the graphics card. It's acting strangely. Normal, the RPM was consistent, 33%. Then when the fan speed max out, the RPM becomes 0. I assume the sensor was not detecting properly? Sudden change in speed. Or overall, the sensor is not working properly hence the drastic change in speed. Still says 33% but the RPM becomes 0 for 2 seconds then show the real RPM, about 2000 RPM. Normal is between 1050-1080 RPM. I did reinsert the graphics card but still happening. I changed the Fan control speed in BIOS and also used some third party software to control the fan but not working. I also had a BSOD yesterday, checked the DUMP file, says driver error. So I removed the video driver and installed a new BETA driver (I know it's bad but I thought it would help). It was Nvidia.
PC SPECS:
i5 - 3450 3.1 GHZ 3.5 GHZ (Ok, this weird, I was checking Properties for the speed, the second speed should be 3.1 GHZ as well but shows 3.5 GHZ, is it overclocking? Even though I didn't overclock. I may have overclocked GPU before but not CPU. This is weird)
16 GB of RAM
Nvidia GTX 770 Zotac AMP! edition (Factory Overclock)
Gigabyte motherboard H77M-D3H
Drivers updated. Removed Nvidia HD audio.
I think this is enough information. Please help. I have searched all over the place, google, Tom's hardware, other sites, but no solution. This did not occur before. Don't know what happened. It just happened all of a sudden on Windows 8 after a month or so? I don't think the GPU is dying, it shouldn't. It's only 2 years old. And I didn't overclock. I shouldn't underclock either. And it's not a CPU issue either at least I have checked. Please help. I know it's long but I shared every bit of information. Do I need to buy a new GPU or is there a fix?
Extra note: Temperature has been cool and consistent between 25-40 Celsius. No overheating.
No gaming, just idling/web
Ok this is normal:
Fan speeds up: (0 RPM shown)
After fan speeds up:
Thanks.
