I was involved in a discussion in another forum regarding VRM cooling. The question I had was about some PC builds I did last year with a 125 watt AMD 940 X4 in a Gigabyte GA-MA785GM-US2H mATX board with 4 phase power and no heatsinks in the VRM, and a aftermarket tower CPU heatsink with 120mm fan. These PCs are being used just for office work, so I would be surprised if they get over 40% core usage very much.
here is what I was advised: That even with no overclocking and with tower coolers, heat on the VRM area would get hot. The VRM gets little air flow with the tower coolers and actually better VRM airflow with the stock coolers. And boards with 4 phase power and no heatsinks on the VRM, it would hurt the lifespan of the board with the 125 watt CPUs.
What do you guys think of this? I don't want these builds crapping out on me a year from now. Should I install aftermarket VRM heatsinks?
Thanks
