High VRM temperatures

[nbrikha]

I have a Swiftech H240-X on my CPU, a ROG Hero 7, a 4790K and no overclocking. I tried overclocking to 4.6ghz, I was able to get it with under 1.3V but the temps got a little insane for me...higher than I'm used to. First, at full fan speeds and full load in Prime 95, my CPU got to 75 degrees and the VRM pushed past 60 and kept climbing. I shut it down and went back to default but even just playing WoW, my VRM got to 58 degrees. That just seems high to me because the CPU was at 33 degrees, everything stock. 

 

I did let everything cool before, and the temps were like that before. With the addition of the 240X, I'm wondering if I should do some MOSFET watercooling. I'd rather not, because it changes the look of the board way too much and I doubt it's effectiveness. Any thoughts? Are these temps ok?

Seems fine to me... It can handle that (I think. On GPU's it can)

[j.dirona]

Yeah its really no problem at those temps. Although if you did want to overclock I'd probably suggest better cooling on you CPU (such as a water block)

umm, H240-X is a waterblock

Those temps are perfectly fine, shouldn't have to start worrying about VRM's until ~70C, even then I ran my old X58 w/73C VRM's @load for 5 years. Try XTU or AIDA64 for Haswell benching, less stress on components but the validity is just as good.

 

CPU won't hit thermal throttling until ~95C and most people call ~80C safe for long synthetic benches, you're well within the safety limits.

 

If you're really worried about the VRM's you can configure your fans to give max airflow over them, might give you a few C of difference.

Cool (pun intended). At stock everything, the temperatures were not nearly as high after the H240X and I have a sneaking suspicion it wouldn't have been as high still if the heat spreaders were soldered on. I don't want high temps because I generally don't update my rig other than a graphics card once every few years. I just came off my last AMD build whose motherboard lasted me 7 years and I'd like to keep this mobo/cpu combo until well Cannonlake or possibly the tick after into the 7nm node. Originally that's supposed to be 2017 but with the delays I imagine 2019 will be more likely. I'm not too worried about VRM under 60 degrees but it looked like it wasn't gonna stop climbing. Thanks for info guys
