Celeron Skylake vs Kaby Lake = different temperatures - 5 degrees Celsius diff

[btcgolong]

Celeron Skylake vs Kaby Lake = different temperatures...



Skylake G3900 (2.8ghz - 65w) runs at 30c


Kaby Lake G3930 (2.9 - 51w) runs at 35c


Kaby Lake 5 degrees Celsius higher



Same motherboard, using each it's own stock fan that came with the cpus...


small note: kaby lake g3930 fan did make a little noise at the start, but that has gone away

In my cases, the kaby-lakes CPUs (i3 & i3u) are a lot fresher than the Skylakes.
Perhaps your thermal paste/ventirads ?

Indeed, kabylakes are more fresher than those skylakes and if its temperature is more higher than the older one with the same set-up then i suspect ventirads would be the problem here. +5 more heat is unusual thing specially when you do build up the same rig/set-up.

this is due too bad (cheap) design

they use thermal grease between the die and the heat-spreader with the new ones
the old ones were soldiered

This is a pretty meaningless discussion for several reasons. It's a Celeron, it isn't made or bought for heavy
workloads and isn't being used to mine. The CPUs are essentially at idle, try testing at 100% usage if you
want a useful comparison. Clock speeds are different. There are too many other factors like airflow that can
have a significant effect on temps.

In short, who cares if a Kaby Celeron runs 5C higher than a Skylake Celeron at low load.

Literally this, stupid OP....
