On Our Bench: HP Pavilion 570 With a Loud, Overheating CPU Fan Gets a New Cooler (NJ)
A real repair from the bench at Dave's Computers in Somerville, NJ. An HP Pavilion desktop came in with a CPU fan that was revving loudly, not spinning the way it should, and letting the computer overheat.
What came in
A customer brought in their HP Pavilion 570-p026 desktop. The CPU fan was revving and making noise without spinning properly, and the computer was overheating.
What we found
The stock HP CPU fan was on its way out, with dust built up on the blades. This is an older Intel system, and there were not many options for a replacement fan that fits HP's mounting.
What we did
- Installed a new CPU cooler. The replacement is a ridiculously large fan compared to the stock one, but it fits the HP mount perfectly. See our CPU fan and heat sink replacement service.
- Applied new thermal paste between the processor and the new cooler. More on our thermal paste replacement page.
- Cleaned out the dust and checked that everything else inside was in good shape.
- Ran quick checks for malware, as we normally do, in case anything in software was making the processor work harder than it should.
- Ran a quick stress test to make sure the processor was actually being cooled correctly, since a fan that revs and throttles can be a sign the system is overheating.
The result
The computer tested fine. The processor stays cool under load and the PC is no longer overheating.
