Hi,

Just been reading the instructions of the EK 7970 block.
This will be my first EK block installation.

EKWB recommends using small drops of electrically non-conductive (for example: GELID GC-Extreme™ or Arctic Cooling MX-2 ™/ MX-4 ™) thermal grease on each phase regulator (that is being covered with thermal pad) in order to even further improve the thermal performance of the EK-FC7970 LTG series water block.
The above part from the manual.

Q1: Is this necessary / recommended ?
Q2: Has it been proven to help temps?
Q3: When it says small drops on each phase regulator. Is that on the phase regulator itself before the pad is placed or on the top of the pad that meets the block? or to place grease on both sides of the thermal pad?
Q4: Might sound noobie... but what parts are the phase regulators ?

thanks
