GPU Fan Speed (RPM) Fluctuates

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.

Those AMP! edition cards run hot. When it hits 80c, the fan goes to max to drop the temperature.

I have a 670 AMP! and it's exactly the same.

Run MSI afterburner and view the temperatures, you will see how hot it is getting.

Hi Thanks for your reply.


Actually my temperature is cool idling and playing games. Temperature is between 25 - 40 Celsius. So there was no temperature issue.

Check when it's gaming, I don't know if it's only at 40, that seems very low for a videocard

How big is your PSU? Could be power spikes. Otherwise, try setting a manual profile with MSI afterburner and see if it still does it. You can rule out a software issue if a manual profile doesn't resolve the problem.

And I don't know. I was thinking the PSU may be a problem too. Not sure about power spikes. I have 650 Watts. I do have surge protectors....2 connected to 1. And the 1 is connected to the power outlet. Not enough power outlet...Maybe the case? Though I have this for a while now. Is it starting to affect after a while?

Yah, sounds like a messy power setup. Maybe clean up the power bars a bit, and move them to a different plug.

Also, did you try MSI afterburner and adjusting the fan profiles?

Thanks for your reply.

You mean clean the power protectors? Do you think it's a power issue rather than a GPU issue? I mean this didn't happen before.

Just to add, I have used MSI afterburner to check. I adjusted the fan but no working. I did set it to 100% for a while, spin for a while, doesn't work out that well but worked a little bit. In MSI afterburner, I did see something unusual, at least it seems. The memory clock, core clock and memory usage jumps so high in the chart, I only just opened the internet browser. Any idea why it's happening? Is it a driver issue? I reinserted the graphics card again but then my hard drive wasn't detected, had to reinsert it, play with the bios and now I can log into Windows. Though the problem still occurs. GPU fan jumps high on Windows boot up.


Could it be a driver issue too?

Any more help will be appreciated. At this point, I would rather get a new GPU but I don't want to suffer the same problem. I have checked to dust, don't see any in the GPU.

Is it a used card? Those are controlled by the Videocards BIOS, not usually the driver

Hi,

It's not a used card. It's new. Actually, it's been 1 year old if I remember correctly.

So how do I fix the problem? How can I edit the video card bios? What solutions can I use? It's frustrating.

Thanks.

I don't recommend doing anything to the card.

I would only try two more things.

Try that card in a friends computer and see if it works properly.
Try another card in your computer and see if it works properly.

If the fan is still acting strange on another computer, go through the manufactures warranty and have the card replaced.
Don't touch the card BIOS or you will brick the card.

Okay, turns out one of the fans stopped working. So I am going to RMA it. I did try a new power supply but fried my motherboard. So I did a complete overhaul on my PC and got another GTX 770, ASUS, this time, better quality. RMA the Zotac and get another one, so I can SLI.


Thanks for your help.

Oh yeh lol. Now I let my local computer store do all the work lol.

Thanks again. I'll comment your second last post as the answer.
