What RPM fan do I need for an i5-8500 (in an HP ProDesk 600 G4 SFF with a heatsink)?

I am replacing the existing CPU fan. I cannot find reliable information on what max RPM it can do.

Wondering what kind of RPM I should get for a replacement fan.

@IMTheNachoMan,

Your HP ProDesk 600 G4 SFF, looking at: http://h10032.www1.hp.com/ctg/Manual/c06027843.pdf, requires an 8025 (80mm) cooling fan.  You can get one inexpensively via eBay, and I would pick a fan with at least with a 0.40 Amps rating (4.8 watts or more): https://www.ebay.com/sch/i.html?_from=R40&_nkw=hp+8025+cpu+cooling+fan&_sacat=0&LH_BIN=1&rt=nc&LH_Pr....

Hope this was helpful.

But how many RPMs does it need to be?

@IMTheNachoMan,

Don't worry so much about the RPMs, what matters most is the cooling fan's wattage.

When the PWM-enabled fan gets a signal from the CPU to rev up -and thus increasing it RPMs, you want a decent fan motor with adequate power to push the air through your CPU heatsink.
