Not sure how I am going to install the fans on my case..I am thinking about ziptie/twist around the premises.

putting them on the chokes (the blocks) is not necessary but it wouldn't hurt.

also, you would get better heat dissipation with the fans blowing toward/on the blocks and not sucking away

The chokes can get hot but they're not active transistors, they're not in any immediate danger of failing

Just a bit scare of screwing up the airflow in my case that's all .

It's been rather slow here lately
One new horror story on an x4/MSI 870 board.... as expected if you run a 125W x4 on an MSI 870 board, it blew up for the guy.

Work on everything else (including a few of the proposed sections and the new horror stories Google Docs table) has slowed down quite a bit due to school priorities.

However, I'm pleased to announce that a new person on OCN (name unmentioned for now) who knows a lot about VRMs will be soon publishing a new article completely about VRM systems with very detailed information in the Intel section. It's going to take a lot of load off me due to having to correct/update this article all the time, especially in hard times. I myself am very excited about the prospect of bringing more concern to VRMs and user safety to this site. This thread will remain along with my article as it is (with modifications pertaining to the new info thread in case anything was inaccurate), as my thread has a bit more of a focus on how VRM quality will affect user safety, then how they exactly work in detail.

I was just talking about idle/normal activity... I've felt the heat coming from them during IBT/LinX and I didn't even want to touch them.

An engineer who knows what's a good brand of VRM's like we know what's a good brand of components. But I won't get my hopes up.
