Outrageous mosfet temp on UD3H ?

post #1 of 29
Thread Starter 


been running 70% ram and 60% cpu usage for about 3hours now


i cant fin the min-max temp ranges for this motherboard online anywhere and im worried my temps are high



does anyone know where to find the manufacturers min-max temps for the components of the motherboard? i want to make sure this board isnt running superhot, its 2 days old and im already OC'ed up

Dont worry about Mosfets, their rated to work perfectly fine until about 85*C, if over that then stick a fan over them. Your are more than fine but if your paranoid then just stick a fan in there anyway

More like to at least 125C - 150C, and more likely the problem then will be heat conducted to the capacitors.

4+1 boards are most of the time 85*C, more power phases means it can handle more heat overall

so then this board can definately handle more than 85*C smile.gif ?

i get mixed info reading reviews and sites, one says its 6+4 other says its 9+2 one said it was 16+2 lol

i would of bought the ud5h but i got this one only so i could fit my rx240 rad at thet op without crushing the heatsink above the cpu :/

The temps are perfectly fine.

As a side note, phase count presented is most of the time irrelevant and not the actual phase count at all. What actually matters is what the phases are rated at. Here's quote from Sin's UD3H review:

This VRM on the UD3H is very capable; each of its phases has the same capability as 2 phases on most other motherboards. We are talking about up to 60A per phase under LN2 conditions, and an easy 30-40A during normal use per phase here.

That seem right, sepcially because OP is right and it says a diffrent number in all the review, I even saw a 24 power phase eek.gif

The physical evidence also matches it as when the heatsinks are removed they can be counted and it adds up!
