Pigging overclock fiasco !!!

Ok, the heads up is....
....the other day i overclocked my rig to what now appears in my sig below.
Today i decide to put in a brand new Zalman CNPS9500 AT
I put arctic silver v on it by applying a small pea sized blob in the middle, covering my finger with cling film and using one directional motion smeared the paste over the cpu. Seated the cooler as per instructions and rebuilt the rig.
Oh, i also changed out the ram from the SuperTalent PC5300 for OCZ PC2 6400 Reaper EB Edition 4-3-3-15. I checked on the website that the ram voltages should be 2.0v.
So, right now my settings are (as read by EasyTune):
CPu speed = 3149MHz
FSB = 358
CPU voltage = 1.36
Multiplier = x9
Ram Freq. = 875
Ram voltage = 2.0v

Bios reports that the ram is at 2.5

Ran Gigabite's easy tune to check temps whilst running Orthos and CPU-Z.
My cpu temp now idles at 33-35° (slightly higher than the stock cooler), but under load in orthos rockets up to 64°.

I haven't altered the ram timings by pressing ctl+f1, although i did look at it.
I don't get it, my stock retail cooler never went above 54°!!! Admittedly it was at 3006MHz not 3159MHz, but still, with a much better zalman you would think it could compensate.

Another thing is, on the DS4, there is a PWR_FAN (with 3 pins), a SYS_FAN with 4 pins and a CPU_FAN with 4 pins. I plugged the zalman (the connector has 4 pins btw) into the CPU_FAN and it didn't even seem to turn on. The cable hardly reaches the SYS_FAN, so i'm using the PWR_FAN (as i usually do) with one pin hanging off unconnected so to speak. It works, but should i be using one of the other 2?

Not totally sure what i'm doing wrong here. So your greater knowledge would be most appreciated.

Thanks
 
Bugger! The method i used was from one i found linked on here somewhere, where i smeared the paste all over the heatspreader with a cling film covered finger.
So according to the 'proper' instruction i just put one one very thin line down the centre and let the pressure of the cooler pushing down onto it force/squish the paste outwards across the heatspreader?

Nads! :(

Thanks though, will try it. ;)

I wouldn't bother redoing it if you did it like you said, the difference will be nothing. The instructions on the website are just for guidance really and doing it your original way to their way is little or no difference.
 
well....something is ballsing my temps up. I was expecting great things from this aircraft engine of a cooler i just bought.
Gonna have to try it before i launch it out the window.
There may be something inherently wrong with the way i apply thermal paste cos my Q6600 runs at 49° idle, even after changing the stock retail fan for a freezer pro 7 (made no difference at all). And now this issue with my E6600 and the Zalman...?
 
Could it possibly be your case temperatures? Maybe from your graphics card, the heat could be rising straight up to the CPU area if it's a card that doesn't get rid of it's heat out the back of the machine (ie. dual slot cooler). Might have bad airflow overall in your case in the CPU area.
 
I would say a pea sized blob is too much TBH, a grain of rice sized blob would be nearer the mark IMO.
Too much past will not help, also be sure its seated even, bigger coolers tend to need more care when fitting.

I also concur with flibby, nvidia's HSF design isnt that efficient at getting all the heat from the graphics card out of the case.
 
hmmm...ok , actually the paste was more rice grain size than pea tbh. The cooler is totally screwed down to there is no slack.
The Lian Li PC-7 case has always given me good cooling. Point is, the zalman isn't performing much better than the retail cooler.
Temps at idle: system = 39, cpu = 33.
 
Lol, well, i have a E6600 @ 3.2Ghz and a warmish room.
What gets me is how fast the cpu loads up to 64° from idle'ingat 33°.
2 of the case fans on my PC-7 are turned off cos they make a hellish racket. They seem to be riveted in so i can't figure out how to take them out to replace them.
Any offers?
