CPU Heatsink is never warm

NickB · February 19, 2016

I have a Intel Core i5-4690k, with high quality thermal paste from Artic 5 (or something like that), and a Cooler Master Hyper 212 Evo CPU cooler. I touched the heatpipes that are really close to the CPU and they aren't even warm. The CPU is at 25-35C on idle and 50C at full load.

I wouldn't really go around touching heatsinks but those temps are fine.

this means the cooler is doing the job of cooling the CPU

if the whole thing is really warm

then the fan is going bad

Temps are good on the chip...don't worry about the heatsinks. They are clearly working just fine if you are only 50C under load.

That would mean that heatpipes are working. The way they operate is that there's some liquid with little air bubbles inside. Liquid transfers heat from chip to top of fins while dissipating heat to fins. So pipes should be coolest right next to chip or top most of the heatsink.
