Hello, I have a question regarding cpu upgrade, i saw other forum topics that suggest that xeon e5-2600 series are supported on t3600 however i want to make sure. I am considering between E5-2697 v2, E5-2690 v2, E5-2687W v2 and E5-2680 v2. I have the 600w psu version in my t3600 and cooling is not a problem as fans are at high in room with about 5 degrees. Is t3600 able to handle those cpus if cooling is not a regard ? Thanks for help.
T3600 cpu upgrade, without regard for cooling
