Arctic Announces FREEZER 33 TR Cooler for AMD Ryzen Threadripper

[uuuaaaaaa]

That board has 12 phases and 300 W over 12 phases at 1.2 V is around 20 amps for each phase ... and it seems either a) those mosfets at 105C loaded with 20 amps lose their efficiency and skylake x throttles b) they heat up the whole socket and cpu throttles
Either way those boards are ready for phases using integrated power stages that can do 30 amps up to 130C ... beats me why they cheaped out in that area when those are norm these days

Each VRM phase for the VCore or Input Voltage and System Agent uses an IR3555M 60A fully integrated PowIRstage which are best in class. Each PWM phase is doubled by an IR3599 doubler/quadruple.

The motherboard's VRM is also using best in class power stages and PWM, but I am unsure of the current capabilities of the inductors, and the VRM is five phases doubled to ten.

It's completely true that I didn't read the review and just drew conclusions from the youtube video, my question then is if each phase is rated 60 amps exactly how does it reach 105C loaded with 20 amps?

Well, dissipated heat depends on the regulation frequency too, also it's MSI, which is known to be in love with cheap components like nikos mosfets. I would not be surprised if they used good mosfets with bad supporting components for that circuit combined with a very poor cooling solution.
