Will the Motherboard choice help CPU temps?

post #1 of 8
Thread Starter 
Guys, I am having problems with my CPU temps. I am wondering if I switch to a different mobo, P35-DS3R/P will my CPU temps come down?

Ambient = 22

IDLE:
Real Temp - 48 and 44
Core Temp - 51 and 49
ASUS PC Probe - 49

LOAD
Real Temp - 54 and 53
Core Temp - 63 and 62
ASUS PC Probe - 68

No the motherboard will really make no difference in your processor temps, unless something is wrong with it.
I'd check to make sure that the voltage is set to what it should be, and that your heatsink is seated right (correct amount of thermal paste, ect). Because those temps seem really high.

Thanks guys, I have reapplied the Thermal Paste and the HS multiple times and the temps are always the same. I am thinking I need to buy a new cooler in hopes the temps come down. I have thought the MOBO would make a difference.

Maybe not so much the motherboard choice, but the chipset the motherboard uses definitely can. Some chipsets will let you overclock a chip further on a lower voltage than others, and that will end up affecting your temperatures.

Guys I did some experimenting. I applied AS5 on the bottom of my AC Freezer 7 Pro in a very thin layer with a credit card. I then stuck it on my Proc and it looked like it only left residue on 2 sides of the proc. Like the picture I have attached. This does not seem normal to me. I figure it should make contact better than that. Has anyone else experienced this or am I doing something wrong. I have to apply more AS5 to make contact so I figure this has something to do with my temps being high?

Well, i've got one question... did you just set the HS on your CPU, or did you attach it like you would when your installing it? Because the mounting pressure will help the HS and the CPU contact better (there has been quite a few threads about "homemade pressure mods" that have helped the contact pressure, and thereby the temps).
If you mounted it like normal (like you actually installed it) and thats what you've got. then what you've noticed is that either the IHS or the HSF is not flat, which you can solve by lapping them, which would make them be flat, and thereby make contact better, and lower your temps.

This is why you don't spread it out before you install the heatsink.

I attached it as it should be installed. I just "assumed" that they would both be close to flat. I had always thought Lapping was for those temp and OC "freaks" Maybe that is my next step.
