With the accelero extreme 280 cooler, which had a ridiculous vrm sink that helped nothing whatsoever (look sig), the vrms even reached 130-140 degrees celcius. Ouch. Fortunately I discovered this early and have since been extremely careful with furmark (basically nothing else heats the vrms as much). Yes, vrms are supposed to run pretty hot, but getting within 40 c of potential solder melting temperature (hopefully they use higher melting points) is uncomfortable.
Imo this is the primary danger of removing stock cooler, as this actually normally do a great job of cooling the vrms. Be sure to add some cooling for these when using alternative cooling. I made a custom vrm cooler out of my stock GTX 280 cooler.

Yeah. I run at 80c constantly when doing heavy gaming in a hot, badly ventilated room, and there are no problems whatsoever. I choose hot, but not too hot, before noise.
Remember, with my Nvidia reference bios/card (as shown in GPU-z) the card ran at 84-85c at stock clocks/fan profile. Its made for these temps.Edited by Chris Ihao - 1/12/11 at 11:01am
