	I had a spare 40mm fan I put right on top of the VRM and the VR T1 and T2 went from 95C max to 90C. Not much but I will take the reduction. Not that I even normally put the system through this stress day to day.

	If either is using water cooling, it is REQUIRED to place an aux fan over the VRM section of the board. Most AiO Kit manuals I have read state so. AMD does also.

	I have absolutely zero airflow in my PC (except for 1 exhaust as part of the power supply) and I'm looking at 100C VRM after about 10 minutes of prime95 small inplace fft, 4.1GHz @ 1.35v, no LLC (about 1.29v under P95), ~310 watts across CPU. With moderate airflow, it'd be in the area of 80-90C. So yeah if you are overclocking and using a lot of power, it's going to get hot. Like I said, I don't use LLC (don't believe in it, causes more dangers than it solves) so my load temperatures are lower. Edited by ssateneth - 12 Mar 2018 at 9:34am

	I have hit as high as 110 now, running Prime 95 at 1.388v, I am sure people have run 1.40v in Prime for longer so I won't worry about it for now, but still a bit hot for my liking...

	HWinfo64 does not list the ir35201, which value are you looking at? my VR1 and VR2 only get in the 80c or so range. Nothing in the 100c or so except 107c on the CPU under ASRock x399 Taichi also (tctl) and that is the offset the CPU will display as AMD uses that plus value there of what seems to be +27c. Ok, edit now did a 10 minute run and VRT1 and T2 got to 95c. I think CPU id reads the entire VRM and all rails where as the T! and T2 are just for the CPU rail.

	Seems like the reading from HWInfo64 are for the IR35201, or the digital multiphase controller, how is the VRM controller temperatures so much higher then the VRM? Any idea how high it can go? http://www.irf.com/product-info/datasheets/data/pb-ir35201.pdf

	I just checked CPUID HWmonitor and I am also getting 49c, however in HWInfo64 I get those high temperatures (Highest 115 after 10 min Prime Small FFT) under VR T1 and VR T2. Now which is correct...
