vrm cooling needed?

[76561198399520696]

I came to know that the MOSFETs can get hot and somehow affect performance (idk how). So should I be concerned about them? Should I get a top-flow/draft-down cooler over a tower cooler? (sorry, but idk anything about vrms).

Thanks in advance!

Depends on the MoBo and your OC... Unless you don't give us further information we have no correct awnser for you

Ugh, no. I didn't mean any specifics. I just wanted to know if I need to cool my mobo's vrms in general.

No you don't. Mostly it has a passive cooler which is enough for normal use. Unless you OC very high there is no reason to. Manufacturer aren't that dumb to not cool something by default that would need it...

Then should I consider a top flow cooler (like the BeQuiet dark rock top-flow cooler) ?

Nope, Depends on the Motherboard in specific. When you really need it you normally have a passive cooler already mounted there or a combination cooler that also can be used in a custom loop or you use a Monoblock.

So if I overclock, will cooling the vrm do me any favour? (some people say it will increase the overall lifespan of the hardware).

My confusion is, the heatsinks on the vrms do passively cool them. But won't the heatsinks themselves become too hot to cool the vrms under heavy usage?

That's why I told you that you need to give further information on MoBo and the exact OC you doing (especially voltage settings).

RAM has also just passive heatsink and you not having problem with those...

If you push the VRM really to its limits then cooling them could extend the lifespan. But nothing where you have a mediocre OC. If you have a good MoBo and to high OCing then it maybe extend the lifetime a bit in a limit that doesn't really matter as its normal lifetime will be still longer then the time before you upgrade.

Say, I'm OCing a i7 8700k to 5.0 ghtz at around 1.38 volts in a Asus Strix Z370 E mobo (without deliding).

delidding has nothing to do with the VRM. Neither ahs the Clockrate of 5.0GHz something to do with it. But the 1.38V which is still nicely within its limit. Also the Motherboard is more then just fine having a good passive VRM cooler.

using a BeQuiet Dark Rock TopFlow Cooler willa ctually make it worse as you push the hot air from the CPu cooler directly to the VRM. The VRM will be nciely cooled with the case airflow. If you want to go better then this you need to Watercool with a custom loop and use a waterblock for the VRM or a Monoblock. However in your case absolutly not needed.

Ok, thanks! I guess I'll get a tower cooler then.

yeah you oly really need to worry if you went for something stupidly budget like the asus prime p and were hoping to get a high oc out of your hardware for a good long time, or in the case of x299 and pushing their higher core chips to high clocks pulls a crazy amount of power and the vrms get crazy hot and can lead to oc not being stable, but on mainstream stuff, you are pretty safe.
