VRM cooling when using H80

post #1 of 5
Thread Starter 
hi everybody, thought this might help anyone that has an H80 or simular water cooler. as you know most cpu stock coolers blow air down through the heatsink fins and out to the surrounding area. your vrm's are usually right off of your cpu socket, and benifit from the air that is circulated across them from the cpu fan.

if you have upgraded from your stock cooler to an H80 or simular water cooler, there is no airflow across your vrm's anymore. i have seen post where people have placed fans(screwed or zip-tied) to the vrm's to keep them cool.

i have been trying different setups to find the best solution to this. first off, i have my H80 mounted in the rear fan opening in the back of the case. i have the radiator and one fan inside the case and the other fans mounted outside the case.

the waterblock is sitting right at the same level as the H80, and the vrm heatsinks are between the two. i got a piece of clear durable plasic (the kind of plastic that comes on stuff you buy and is a real pain in the butt to open),

i cut a piece that is the same length as the vrm heatsink and about 3' or so wide. i bent and molded the plastice so that it's flat and then goes into a curve forming a right angle. got some clear tape(like the 2" wide packing tape) and folded it to make double-sided tape.

place it on the flat edge of the plastic, and then stick it right to the side of the H80 waterblock housing.(making sure that the cupped end is facing the fan on the H80)

my H80 blows air into the case(it's quieter for me that way). now, the plastic should cover about 1/4 to 1/3 of the fan that's on the H80. so the air that the plastic catches flows directly over the vrm heatsink. just a simple plastice baffel and your vrm's will have fantastic air flow and you don't have to add an extra fan.

i hope this helps someone, it sure helped me,,,,,, btw, i also mounted a fan on the motherboard side of my case to cool the back of the socket as well as the backside of the vrm's , i used the stock air fan that came with the original heatsink. i'm running so cool it's not funny, overclocker heaven biggrin.gif , if i get a chance i'll take a couple of pics to put up, have a great one, later thumb.gif

hi, sorry about the format, i'm on a biostar 990fxe , but most motherboard have there vrm's to the left of the socket and under the socket (below). mine are connected with a heatpipe, so it's the one to the left that gets the special cooling

Oh you don't need to worry about that bud. That's an excellent cooler on them. I just have mine cooled by air being pulled across them. Unless you plan on overclocking your northbridge you don't need to worry about it. I've had mine OC'd to 2800 without any fan blowing on it just fine.

This is probably not a new idea (redirecting some main fan flow), but it sounds like a great setup for cooling! thumb.gif
