Buying guide
Replacing cooling parts
Airflow direction
Switch fan trays and some server fans come in front-to-back and back-to-front versions. Every fan in a unit, and its power supplies, must move air the same way.
Thermal material
Fit fresh thermal paste or pads whenever a heatsink comes off. Many HP heatsinks ship with thermal material already applied.
Graphics variants
Laptop heatsinks often differ between integrated-graphics and discrete-graphics versions of the same model.

Frequently asked questions
Why is my server running its fans at full speed?
Usually it has detected a problem: a failed fan, a missing blank, a component it doesn't recognize, or a heatsink not seated properly. The management log in iLO or iDRAC shows which.
Can hot-plug fans be replaced while the server runs?
Yes, in servers with hot-plug fan bays like the ProLiant ML570 G3, where redundant fans keep cooling while one is swapped. Fixed fans need the server shut down.
How do I know a laptop fan is failing?
Grinding or clicking noises, a fan that runs flat out all the time, or a laptop that shuts down under load all point to a worn fan or a heatsink clogged with dust.
