Really hot VRM

RichH · 23 Apr 2013 at 23:13

The VRM is whatever is under the heat sink to the left of the CPU right?

Anyway, mine is really hot when the CPU is stressed. Hot to touch, not skin burning but hot. It already has a fan blowing over (all be it not very hard) and 3 fans at the top just above it exashing though a rad.

Anyone got an ideas on how to cool this? As far as I am aware there is no waterblock for my mobo. Although I would bodge one on if possible.

My RAM is also pretty hot, but not as hot as the VRM, so not so worried about that.

Thanks in advance of any help.

Should be alright tbh.

Waterblocks have been made for your board though

one example:
Watercool HEATKILLER® MB-SET ASUS-P8P67 / Z68 Ni

Sorry for the late reply, but thanks for this.

Following this lead it appears there might be suitable separate blocks as well.

I really only want one for whenever the left hand sink covers. Anyone know if that is VRM or mosfat?

VRM's do get very toasty hence their requirement for large chunks of copper sat on them. If you can hold your hand on them they are fine, they are generally rated for 90c and your system should (or likely will) shutdown if they get too hot.

End of the day, during gaming they won't get anywhere near as hot as they do under Prime95 like I assume you are doing.

Yeah theyre proberbly the mosfets your talking about, they normally have heatsyncs on them that are designed to be cooled by the air coming from your CPU cooler. Just make sure you have a little air flowing over them, or if you fancy water cooling them you can proberbly buy seperate Mosfet waterblocks from EK, i had them on my last mobo.
