New cooler, compound, or motherboard?

post #1 of 4
Thread Starter 
Okay, so I recently purchased a Q9450 for my sig rig. CM N520 cooler and ASUS P5N-D. The N520 was great for my E6500, kept it at 30 C idle 55 load even at 4 Ghz. But I'm having trouble with this processor. Granted, it's a 95W quad so it's going to be hotter than a dual, but here's the breakdown:

First seating, temps idled at 67 C.
Reseated twice, temps stayed the same.
Updated bios from 1204 to 1401 (temp offset adjustment according to ASUS), idles dropped to 58.
Flipped exhaust fan around, temps idle at 50.

So now I'm stuck. I'm not sure if I need to just get a better cooler, or if the Ultra compound should be replaced with Artic silver (does it make that big of a difference?), or replace the motherboard since it's been finnicky in the first place and (may) cause the temps to be higher. Thoughts? Help me please!

BTW these are all at stock speeds (1333 FSB, 2.66 Ghz)

Changing your motherboard won't get you lower temps. Your temps are a function of your heatsink and the air that flows through it.

Your heatsink should be able to handle your chip at stock speeds. Granted it has only 92mm fans; but it has two of them. With four heatpipes it should be fine for a stock chip. That leaves airflow.

Your case looks pretty old. Looks like it came with a single 120mm fan. It has fittings for two, which would improve your airflow. But I can't tell how much the front structures obstruct airflow into your case.

Try this: take the side panel off your case. If your temps go down, you have a problem with your case.

Good cases are cheap. Don't be afraid to get a new one. Also,, don't fall in love with your psu. It's apparently not very good, so you should get a new one as soon as you can afford it. Look for reviews here. They have forums here. You can ask questions and get intelligent responses.

Some powerful fans could help too. I have some 92mm fans powerful enough to tear that heatsink right off your board (ok maybe not but they are loud and powerful)

A bit of an update: The temps across HWMonitor, Coretemp, and Real Temp are all giving me the same reading - 50 42 49 47 across the board. That's at idle with AS5, and I also tried removing the wall but that made no difference which means it isn't the case (I also have a GTS 450 SC and that doesn't go above 60 degrees at load, 57 is the highest I believe) so I'm going to go ahead and rule that out. Core 0 is still hitting 69 degrees at load, but I just applied the AS5 yesterday so we'll see how much the curing process does.

Furthermore, to eliminate other culprits, yes the heatsink is mounted correctly. I have two case fans, one 120mm for intake from the back to feed directly into the heatsink, and an 80mm for exhaust through the sidewall grill (that I mounted inappropriately but it works). I'm going to see about getting a third case fan since there is a mount for it in the front, I originally had the 120mm there with my E6500 and the 80mm at the back, which is the most baffling part of it. Seems that past the third case fan my options are new 92mm fans for the heatsink or an H50, and if those don't work then perhaps I should just switch it back to the dual core. Man, I was really looking forward to buying another 450 for SLI
