GPU fan control issue?

[matt0725]

Hello everyone, i am trying to figure out the cause/fix to my GPU fans spinning up to max and then spinning down to the regular rpm constantly when under load. Im running an EVGA 2080 KO.

 

This has been happening more and more often lately, and I am trying to figure out the cause, and if this is something to worry about with the card. More than anything, at full speed the fans are loud enough to be really annoying, and the constant tone changes are also annoying. This has been over the course of months so i don't think any particular windows/driver/software update causes this. Everything is fully up to date currently. 

 

When gaming, how often it occurs seems to depend on the load somewhat. on Rocket league, the fans spin up intermittently, it may go 5 mins without an issue, it may happen twice within a few seconds, then not for 10 mins, etc.

This week i downloaded Ark survival evolved, and within that game, the fans spin up literally non stop between full speed and the normal 60-80% range depending on temp. Trying Furmark 2 gave only 2-3 fan spin ups over about 20 minutes. Other games are hit or miss but i don't have a ton of play time in other stuff recently to say for sure.

 

For temps, the hottest the temp logged in gpu-z reads 75.3c, and the hotspot is 106.8. (this is 20mins of furmark2 4k +opening ark for ~5mins) I also noticed within gpu-z that the fan speeds seem to not be 'commanded' to 100%, but the RPM (and my ears) show it is. gpu-z will still report the fan speed% as 60%, but i watch the rpm go from ~2500 to 4000 and return, all without a change on the fan speed%. Issue also persists if i use the nvidia app or msi afterburner to lock fan speed to say 80%, it will report 80%, spin the fans up to 2800, but occasionally max them at 4000rpm, or set a curve manually in afterburner, etc.

 

If i need any more info added please let me know, thanks in advance for the help! issue is driving me crazy

have you ever repasted the gpu?

you are the second person today reporting fan flutuations on 20 serries gpu, it makes me wonder if this is a driver issue or something or an uncompatable update

see yourself:

I have not. I had ordered thermal paste and it showed up literally 5 minutes ago. I feel like with my temps under control as it is though that it may not be necessary

That is odd, and I’m not sure how I missed that thread. I’m going to try rolling back to a really old driver right now before I repaste and see if it makes a difference, although I’ve had this issue for minimum 6 months now though, maybe as much as a year

amd and nvidia both have driver issues for older gpus, i seen it before but it is the first time for fan problems because of a driver if it turns out to be driver,

I just went back to the oldest driver on the nvidia website, from October '24, and the fans spun up the same within 5 seconds of opening a game, so now im going to go for a repaste. Thankfully i've done watercooling before so im familiar with the process, will update on here once done and tested

Well, repasted with artic mx-4, i've dropped 20-25c hotspot depending on the workload. 107 max ive ever seen prior to 86 max now after 5 mins on furmark+10 mins of ark. gpu temp overall stayed the same at 75 but its clocked higher now. I get ~10fps more in furmark and probably 20+ in ark. Fan speed spiking hasnt reappeared yet, and would 100% have happened many times already within 15 mins before.

 

The paste was still soft in the middle but had started to dry and get flaky around the edges, which i guess is enough of an issue to cause this.

 

Im guessing the nvidia card has some kind of safety built in for a temperature spike that the monitoring software doesn't even detect/report, as all of my temps were within spec before this.

glad to hear you fixed your gpu, maybe hot spot was triggering this wired issue, think of the ods two people with close enough gpus have the same problem  at least you can use your gpu now, i hope that other person knows how to repaste a gpu and manages to do it, one more happy gamer is one more posible solder in call of duty

Glad you could fix your issue! I would've also suspected the paste, as 107 on the hotspot is a LOT when your overall GPU is only at 75. I had an RTX 2060 that I only had for a year and a half, repasting it after that already brought the temps and fan down quite a lot. Same with my GTX 1660Ti mobile that had its paste totally dry after just a year and a half
