I have a TRX40 system with not very good VRM cooling - ASRock TRX40 Creator. So far it is serving me well, but I wonder about putting a 64 core CPU in it.
I’m not convinced that big aluminum block without increased surface can be very effective as a radiator in that scenario. I’m also not a big fan of small fan that is slapped on the aforementioned alu block.
Would putting a proper small finstack radiator with 40mm Noctua fan on every VRM section be a good idea?
There are no custom VRM heatsinks available, so some ghetto modding or recycling might be necessary. I consider (re)using:
- laptop cooling
- RAM coolers with copper heatpipes
- old high end board VRM coolers
- cheap Aliexpress custom heatpipe+finstack combos
