very annoying fans rev up when i open a web page?

[GOW2]

So my daily PC runs a stock i7 8700 on a 120mm AIO with a room temp of 22c. Anytime i open a webpage to even post this message the PC fans will rev up for a sec then rev back down. The CPU stays around 65C at 30%-50% load when used with spikes up to 76c-80c

 

I have the fan profile set to silent in the Asus bios. I have tired re-setting the AIO.

 

Any ideas?

Is it your CPU fan or case fans making the noise? If it's your CPU fan, check what temperature your CPU is spiking up to when you load a web page, and manually adjust the fan curve to have the fans not ramp up until your CPU gets above that temp. If it's your case fans making the noise, you can either do the same thing as suggested with your CPU fan, or you can change the case fan curve to monitor motherboard temps instead of CPU temps, as those won't fluctuate as much doing small things like loading a webpage.

I have all the fans set to low in the bios at a certain temp you can not go lower then. (70c)

 

All the fans rev up when you open a page. The MB is controlling all of them as i can watch a spike in all the fans anytime i open a page when watching there RPMs in the asus ai suite. Temps will spike over 76c for a sec.

 

See the pic below that little spike is just from opening a web page in chrome youtube for example.

Neither your CPU or motherboard should be spiking that high just from loading a webpage... What do your idle temps look like?

They are 60-65c keep in mind that my cpu always has a load of 30%-50% since it runs camera monitoring software 24/7

You can install AI Suite 3 which has Fan Expert and make custom fan curves.

That is what i am using. What is best for a PC that is on 24/7 water or air?

Given only that information I would pick air.

 Yeah not used for gaming. Is it because air is less likely yo fail?

 

Right now i'm using a corsair 120mm cooler. It should be fine for a cpu that is only 65 watts.

Your temps are overall higher than what they should be for 50%. Have you tried to reseat your cooler and change thermal paste? I would say that seeing temps over 50-60C for that kind of load is one issue.

 

The other issue might be controlling. Can you post screenshot of the fan curve? I think that you get the ramp up because the temps go over certain threshold where controls think CPU is overheating (probably 75C).

You where right 75C.

 

I found the issue it was a bad fan splitter! Now i'm at 51c at 30% load even with a low fan speed no more revs!

 

I ended up taking it apart and noticed a wire loss on the fan splitter. I even got rid of all the dust.

Was it a fan splitter connecting the CPU Fan or Chassis Fans?
