My VRM's are causing the system to shut off power if I increase the voltage core on my CPU. The HS is scolding hot to touch. Any tips on cooling it down?

I don't have any fans directly pointed at them, but I would assume air is being passed in that section. Also, what do you mean what are they set to? If you mean the bios, vrm is on auto and as for the fans, they are also on auto.Originally Posted by NoGuru
Do you have any air flow over them? What do you have them set at?

Go in the BIOS and set them to a lower power start and see if that helps. Ram can interfere with the air flow as well depending on the airflow in the case.Originally Posted by BradleyW

It really depends on the OC but better to have a slightly less OC then have shutdowns. I would guess you may loose 100mhz.Originally Posted by BradleyW
By settings a lower power start, will this reduce my chances for gaining a decent CPU overclock?
btw, it is good to see you after all this time, and thank you for the help so far.

If you're running higher than stock voltage, and a full load of RAM, you might need some active cooling to keep the VRM cooled. A picture of your case and/or an accurate description of your case and cooling arrangement would help figure out the best advice.
What kind of overclock are you running now? If you're running a 3930K or 3960/3970X over 4.3-4.4 GHz on that board, you might be well past the design limit of the VRM. The VRM is built for 130W TDP processors, you might well be pushing 200W+ through it.

I can set the Wattage limit so that's not the issue. The board is just getting seriously hot for some reason.Originally Posted by hammong

One other thing to think about is PSU output voltage. Check the 12V output and see if it's within ATX specifications (+/- 5%). If it's too high or too low, the VRM may be shunting excessive power.
You never did say what clock speed you're running that 3930K at. There are enthusiast boards with better quality/higher capacity VRMS for people that want to push their CPU to the power limits. I can't comment on the VRM quality of your particular GA-X79-UD3 board. Also, there is this interesting link, Gigabyte recalled some UD3 boards due to faulty/underperforming VRMS:

The PSU is fine as I've tested it on several systems recently. I am only running a vcore of 1.35 @ 4.2GHz.
Also, that recall was a while ago. I only just got this board a few days ago from one of UK's leading retailer in hardware. They also state at the end of that report that the hardware was in fact fine, and the F5 or F6 bios was to blame.

The VRM's weren't faulty, it appeared that it was a firmware problem so they released a new BIOS (F7) and HiCookie made a Record on the board.Originally Posted by hammong

That's right, however I'm still finding it hard to cool down the VRM HS on this board. I pointed a fan at it and everything seemed fine, however as soon as I put the side panel on, the CPU throttles or the system just shuts off.Originally Posted by adridu59

They're probably getting hot because you're not blowing air across the mobo with the CPU cooler, because of you using WCOriginally Posted by BradleyW

If you did there is your problem, make H100i to push (as originally made) and insert 200 mm fan on top to exhaust hot air.
If the 200 mm fan is still there then something is wrong with your airflow.
Other option is that you got faulty board. Here is one like yours in this popular video:
As i see you have HAF-X case and H100i cooling in push pull. One question, did you removed 200 mm top fan in order to make push pull ?Originally Posted by BradleyW

I set a NF F12 to blow onto the upper half of the motherboard but my gear is still getting too hot and the speeds are throttling.Originally Posted by ACHILEE5

all x79 board's are pretty notorious for running hot vrm's I literally had a fan sitting about an inch above mine blowing air right onto it, until i finally said hell on it a bought a block for them. All I can really suggest is get a fan resting on your cpu block tubing and aim it up towards the vrm's, that way you can get as much possible airflow on them.
Alternatively if you can find them use some of those antec spotcool fans, it was easier for me to use a normal fan due to my board lying down on my test bench would be a pain in a tower to get a fan to rest.
