Hello everyone, my problem is the followying:
I recently bought a new cpu (I7 - 4790K) for my pc which was previously running with an I3 - 4330, from the momment i started using it, I noticed that it's fan wasn't doing the initial rev to it's max and back to normal thing like the one on the I3 did... When i booted windows i noticed the cpu was running at 95cº which made me instantly shut down my pc... when i started up again, i locked the cpu at 3.2 GHz... that solved the problem untill i got a new cooler, which is the Gamer Storm Lucifer V2 .... I am currently running the cpu with a max clock speed of 4.2 GHz and the fan of the new cooler still doesn't go above 1300... I'm sure it can do more but i can't understand why it doesn't. i've tried speed fan and messing with the BIOS settings, but still.... it doesn't go above 1300RPM... what should i do?

I'm considering just removing the PWM wire and run it at max voltage, but i don't know if that's a good move.

P.S: I want to run the cpu at higher clocks for gaming and for video rendering

The BIOS probably considers 60c perfectly fine, try a stress test and warm it up a bit and see if it speeds it up but really if you can stress test it at under 80c then there's really not anything to worry about as real world usage almost never matches that.

There should be a few different FAN profiles in BIOS and often an option somewhere to run it at max speed permanently, have another look. A performance preset should clock the fan faster than a balanced or quiet one. Trust your BIOS though, if it doesn't think the fan needs to run faster then it probably doesn't.

you plugged

that's a nice little board.

the cpu fan (just from design and not looking at any specs/performance) does not look like it's built very well, better CPU coolers will have a copper heatsink (part which touches the CPU)

are you running your CPU fan through the header on the motherboard above the CPU? I think the battery is next to that connector.

You could also get a Molex adapater for PSU>FAN but that will result in the Cpu fan running 100% all the time, other things would be a Fan Controller unit which you could adjust fan speed yourself (these things are just suggestions, they are not a solution)

Alright... thank you to everyone who answered... i got kind of paranoid when i say my new cpu at 95c ... and since i read around that stock fans would go up to 5k RPM i forgot to check how fast the custom cooler's fan would go...

I'll be keeping my cpu at 4.2GHz which is the sweet spot in my opinion.
Once again... thanks for taking some time to answer this.
