I just got a i9-10900k and without much of an overlock is running at 38-42 C when idling. Is this normal or should I bump up the fan speeds?
 
Solution
Idle temps are irrelevant, unless there is a problem with your maximum temps, THEN, and only then, might idle temps matter.

If your idle temperature is 45°C but your maximum temperature under a FULL load, such as running Prime95 (Small FFT option, all AVX options disabled) for 15 minutes, is 85°C or less (Preferably 80°C or less), then there really isn't a problem.

If however your idle temperature (And we have to be careful here, because what exactly IS idle temperature might vary from system to system.) is 45°C and you are exceeding the maximum recommended temperature under a full load, THEN the high idle temperature is indicative of a cooling problem of some kind, whether that is a poor mount job with incorrectly installed or loose...

38-42°C doesn't seem out of line for this CPU, especially if you are not exceeding the maximum recommended temperature.

It would probably be a really good idea for you to read this:
