I recently installed a Waterblock for the VRM mosfets.
I was expecting the temps to drop a lot.
but on the first test on clocking with 1.52V, the VRM still throttles the CPU.
lucky is that if I point a fan at the Mobo northbridge, it solves the throttling....
but anyone know why watercooling the mosfet is not effective?
I checked that I didn't do anything stupid.. (like forgetting thermal pads etc)
Just am majorly disappointed at an investment that has no value. (ended up pointing a fan at it.. again.
any insights on how to cool the VRM better?
please share your experiences.

airflow I have fan in front/side/bottom blowing in.
top and back radiator radiates out.
water goes:
Res->pump->120.2 top rad->cpu->120.1 back rad->VRM ->SouthBridge block -> bottom 120.2 rad -> GPU -> res.

Thanks bluezero5 for the details!
Allow me to point out something to you: You're running a 3930K CPU on 1.52V Vcore - that's meaning that it's getting really hot! Now, you'r saying that your temps are fine ("not even above 70C")... but imagine, where all the heat produced by CPU is going... into the water - right? That rear single 120 mm radiator would barely dissipate all the heat produced by a 3930k at 1.52V Vcore... Which is meaning that your are sending preheated water on the VRM! So the VRM is still not cooled effectively... 😞
Without dismounting the tubes, you have basically two choices: reduce the voltages (Intel's safe specs are 1.4V) and/or increase the heat dissipation on that rear radiator. The first option is up to you... certainly would reduce the heat production, but if you like those high voltages... For the second option, you could modify the overall airflow by adjusting the fan speeds, those forcing more air through the rear radiator.
