So I still have some parts from my original build years ago and they include some budget components - specifically my z97 PC Mate motherboard. For a couple months I was running my 4690k OC'd to 4.2 at 1.26v (Lost the lottery) stable, I only had 1 bsod in the like 3 months I was running it here on pretty heavy usage. About 2 weeks ago I swapped to a new case, Phanteks P300 and bought a h100i Pro to replace my evo 212. Temperatures are good on the cpu at 4.2 under stress tests, like 62c max over 15 min test with realbench. Even so almost daily I was getting a bsod or just heavy stuttering and lagging despite my temps being solid on the core package. What I think the culprit is, is my vrm temps. My theory is that the z97 pc mate just has shit vrms - as far as I could find it only has 3 true power phases and the heatsink may not be the best since its more a block with very thick fins for poor heat dissipation. Before with my evo 212 I likely had significantly more air running over the top of the vrm heatsink which was keeping my OC stable despite the heat on the vrm being high. Now with my aio the only air going by the vrms is the single exhaust fan at the back.
So my question is essentially is the instability of my overclock more so the poor build of my motherboard. Assuming it is, I should be ok when I upgrade in the future to a new motherboard cpu as long as the motherboard has good vrms and plenty of power phases to spread out the voltage and keep temps low. OR should I consider flipping my h100i for a air cooler and assume that no matter the quality of the motherboard I'll get similar instability/throttling on my vrms as long as im using an AIO in the P300 case
