Necessary to get air to VRM heatsinks?

Go to solution Solved by Lemtea,

No you should be fine, that board has a decent vrm and a i5-8400 does not pull that much power. 

I have the ROG STRIX H370-I GAMING motherboard, and I have the Cryorig C7 cooler. In the motherboard I have the Intel Core i5-8400 installed, all inside the Fractal Design Node 202 case. If examined carefully, the motherboard has a VRM heatsink on the left under the metal shroud, and I was wondering if they needed air from the CPU cooler to go there. Currently, I have my Cryorig C7 cooler mounted with the fins vertical so that the hot air may exit the Node 202 ca se. I've attached an image of a diagram of how the fins are oriented, and air doesn't get to the VRM heatsink you see on the left side of the mobo. Since I have an i5-8400 and I can't overclock, should I be concerned?

 

Thanks in advance!

So I assume I should only be concerned if it was a Z370 board and I was overclocking right?

Yes, but even then only if you are pushing really high voltages and clocks.

To add, VRMs rely mostly on passive cooling from CPU cooler and case fans. So as long as your CPU is fine with cooling, so should VRMs be. I haven't heard of any major issues in that part, there was some during Haswell and DC era with H80i and other 120mm AIOs. Those were, at worst case, covering VRMs and not providing enough airflow over those parts.
