Cooling Issue

[jonpaul37]

Ok, here's yet another weird one.

I had an Arctic Cooling Freezer Pro 7 on my setup. (which i will post below)

Took the AC out and put in a XIGMATEK HDT-S1283 (with the retension bracket) and my temps have RISEN! yes, they went up!

I have done this before and with the retension bracket it is tough to say that it is not secure on my CPU.

I used Acrtic Silver for the compound.

Anyone have any ideas?


Temps:

AC Pro 7
@ stock 31 idle, 51 load
@ 3.6 31 idle, 51 load (no voltage increase)
@ 4.0 38 idle, 56 load (voltage to 1.28)

Xiggy
@ stock 41 idle, 61 load
@ 3.6 41 idle, 61 load (no voltage increase)
@ 4.0 45 idle, 67 load (voltage to 1.28)

System is as follows (same exact settings used with both heatsink/fans)

MoBo: ASUS P5Q Pro
CPU: Intel E8400
RAM: 4 GB G-Skill DDR2 800 PC6400 @ 4-4-4-12
Video Card: Sapphire 4870 1GB @ 800/1000
PSU: PC Power & Cooling 610 Watt PSU (forgot model #)
Hard Drive: WD Caviar Black 640 GB (very nice drive BTW)

how did you apply the thermal paste, the correct(the way i always do it) way for a direct contact heatpipe, is to apply the as5 to the heatpipes in lines down the pipe. ask luprion for more help has he has one.

Did you clean off the cpu/heatsink to get rid of the previous thermal paste, and if so with what?

I have no experience with those retension brackets but did you put it in correctly. Or use too much or too little thermal paste.

hmmm... ok, i have thoroughly cleaned both the CPU and the Heatsink before application. (i have the arctic cleaning stuff and purifier)

As for applying the arctic silver down the pipes, i have not done that, i just applied onto the middle of the section where the pipes are and that's it, i didnt smear it or anything, just applied and attached to CPU...

yea def try my method again.

Also remember as5 does take a little to set, not going to make up 10C though. I didn't research this but I would bet that your AC pro 7 has a better fan than the xiggy. More air moved = better cooling.
