Just got "Intel Xeon W-3275 QS CPU 2.5 GHz" and when run on windows cpu-z stress it get throttle by half after 10 - 30 min.

What's your overall experience with QS CPU? Apart from this throttling issue (resolved) is there any other problems? Is it 100% stable?

have to use mac fan control - without got trotting

then tested few hours under heavy load no issue

 

[Frixo Cool]

Do you need Macs Fan Control only in Windows?

 

[someuserxsvr]

yes on windows yes was trotting without fan control
only when do heavy load
dont remember if was tested on macos

any way don't use it as is to sell as something related to virtualizaton was banned by apple firmware
