What's the max spin speed for a i7 4790k stock fan?

[GethPrime]

Hello, what's the max stock fan spin speed for a 4th gen i7 4790k, should I be worrying if RPM reaches to 1800?

Thank you

GethPrime, Thank you for posting in the Intel® Communities Support.

In reference to your inquiry, just to let you know, the Intel® Core™ i7-4790K Processor is under status of: End Of Interactive Support / Discontinued, as you can confirm in the following link:

Still, as an option, you can always run the Intel® Processor Diagnostics Tool, if the processor passed the test, it means it is working fine:

If I remember correctly, there were three versions of this heatsink-fan unit, with fans from three different vendors. I am not sure what the actual maximum speeds of the fans actually were. This is actually not important and a sidetrack.

What you need to be looking at is the temperatures of the processor and the duty cycle being sent to the fan. If the fan is running at near-100% duty cycle and the temperature is sitting in the 90's (or worse reaching 100c), then you are in trouble. I would be looking at replacing the Thermal Interface Material (TIM, heatsink paste) at this point.

Hope this helps,
