[SOLVED] Ryzen 5 3600 boot temps too high

[Benton92]

I spent all day building a new pc with a Ryzen 5 3600 and an NZXT Kraken x63 AiO. When the system was ready to go, I booted it up for the first time and the cpu temps in the bios were higher than I expected (45-52 degrees Celsius, very high idle temps for a water cooler while idle). I checked to make sure the CPU and pump heat sink were making full contact with the thermal paste, and they were. However, im still getting the same temps. Is there something else I can check?

Normal for bios. It is more 'active' than idling on the destop.

So is it a good idea to install windows and check temps afterwards?

Normal temps are 10-15C above ambient room temp at idle and 65-70C under load.
Bios can read higher temps during initial boot up, BIOS is a simple, single-threaded program, so only a single core gets boosted to 100%.
Use HWInfo64 to measure CPU temps at the Die for a more accurate assessment of CPU thermal.

Yes, but check load thermals. It does no good to get hung up on idle and bios thermals with Ryzen 3000 and later; it's just the nature of those chips.
Their behavior has caught MANY people off guard.
50C idle isn't any more dangerous to these cpus than 80C load: not at all.

I was able install windows and temps are normal. Thank you!
