H7 fan speed..

[adham.]

Hey about a day ago my H7 started ramping up it's RPM on it's own.

It was running on 500~550 RPM now it's 750 to almost 800RPM (idle on both)

The CPU temps are the same...
What's up with that?

No BIOS settings changed.

maybe the thermal paste hardened or the fan is clogged with dust. did you clean it out recently?

Yup, check your fan curve. could be the TIM crusting up and the fan ramping up to keep CPU temps the same.

It's 3 weeks old. Dust is not that fast.

Fan curve is on Auto. I applied the CP7 thermal paste that came with it and it was working fine. Today only that i've noticed the higher RPM.

true.

 

since your temps stay the same eventough the cooler ramps up, something must be going wrong tough. did you overclock recently or something? also, did you check your mounting? maybe try to give it a little wiggle to see how secure it is.

I have a non-overclocable CPU.

I gave it a slight wiggly wiggle and it's secure and tight in place.

Seems to me the only logical thing would be the paste. Would reapply it now and see.

You should set a custom fan curve in the BIOS or in lieu of that, through Speedfan. You can set the fan to idle at certain low temperatures and then ramp it up as it reaches the highest temperature you're comfortable with. Speedfan is a bit hard to set up but it's a wonderful program imo.

Its reacting to some software or background process raising CPU temp tad over whatever the limit is. The raises are too fast for you to get glimpse without good graph monitoring. But it will sound like fan ramping for no reason as it slows down once temps are back down.

Problem solved guys.

Without even doing anything.Silly me never opened task manger to see if anything is doing anything due to the CPU never actually showed any signs or ramping up it's speed.

And it looks like Windows 10 defender thing has been doing stuff behind the scenes which got the CPU to 15 or 10 percent. And i assume this heated up the CPU like 5 Cs more.
Then the H7 would ramp up so the temps would stay the same.

I have only noticed it today after a series of fan RPMs going up and down in less than 15 secs.

That's pretty dumb of me, But thanks to everyone who replied to my post.

Edit: I'm going to mark my own reply so the whole topic is marked as solved.
