New CPU cooler prob?

I just recently bought the Zalman CNPS7000B CPU fan for extra CPU cooling. While installing it, I didn't bother to replace any of the thermal grease because I thought I already had enough on it and it was fairly new. There was enough on it that you could barely see the dye. When I booted my computer, the temp had was 5-10 C higher than my original stock heatsink and fan. I don't think it's the product and Fan Mate is on normal and it was installed correctly so could it be the thermal grease? If so, am i ok using the stuff they gave me or do I need to buy AS5?
 
Firest off, you're always suppose to change your thermal paste when you remove the heatsync. How much of a difference this will make, I don't really know... But it certainlly couldn't hurt to reapply some better stuff on it.
 
Ok, well I reapplied the CPU with the white stuff they give you and I used the 'apply on the center then allow heatsink to spread it' method and I'm stil realitiviely getting the same readings.

BTW, I do no recommend getting this cooler if you have an AMD because it was a real #@$%* to install. (You may have to completely remove the mobo to install a backplate.)

I think I found out me problem. Instead of Fan Mate, it's more of Fry-Your-CPU Mate as when I plugged it directly to the mobo, the temps dropped but now I have to go buy AS5 cuz I wiped it off and applied that white crap....

The problem still is that it is at the same or higher temp than my stock heatsink....

The first mistake right off was not cleaning off the used compound completely with a denatured alcohol and letting it dry. The Big second goof was not using Artic Silver 5 for sure on a Socket 939 model cpu. The 3rd goof was knocking Zalman coolers! :P

After you evenly place a small glob of AS5 in the center of the cpu you bring down the sink very evenly and lightly to see the AS5 spread itself. Run the system for only a few hours to allow the compound to be heated for a period of time and then shut down for several. That will allow the compound to firm up. After a few weeks of use the compound will have bonded thoroughly.
 
....huh, I guess time will tell. Funny though, when I replaced the stock thermal grease with AS5 on my old sotck cooler, i got immediate results....
 
On a new build here the AMD 3500+ climbed right to 60C when left running until the overheat protection shut it down. But that was monitored to see if there were any faults with that feature. The temps are always seen under 40C when gaming. The only thing that sees roughly 41C is Windows Media Player when running that for 20 minutes or longer with the screensaver going.

On the stock cooler the pad was probably left inplace I imagine. That's preformed thermal compound there. So your temps didn't jump up. With just the application of a new coat of compound that has to bond a little before running the system for any extended period of time to prevent overheating.
 
I didn't have a thermal pad, I had that white crap, and ya I dodn't have any jump in temps... How long does it usually take to set in?
 
The first night is what saw the high temp right after applying AS5. I mean closing the case up and powering up on the spot. The system ran straight until the protection circuit did it's job. Generally you only run the case for those first few and then run normall after it sits for some period of time.

To see the first good bond a few days total there with average use and a few weeks go by before the compound is firmed up as far as it will go. On the old board that recently crapped a Zalman cooler was just thrown on when a different 3rd party cooler fan went seeing some high temps! Try 85C! the max of the Socket A model there. The rush to a local store saw Antec's brand of paste supposedly rated for higher temps.

The Antec paste was still loose and smearable a few weeks later when the new board came in to replace that one. The Artic Silver when first was applied later bonded fast when a second model Zalman came in for the new cpu. Artic Silver has a certain percentage of ceramic mixed in while the antec was strictly the silver. That gives it a faster bond there.
 
Finally got some AS5 and reapplied the heatsink and now the temps are down what I had orginally so hopefully, after time, they will go down even lower.

I don't know what you're talking about PC eye about a heat spike because this is the second time I've applied thermal grease and I still getting normal temps....

You didn't try the same thing to see your temps climb that's why. :P I fired the new build up on the spot before the AS5 even had a chance to bond in order to test the overheat protection. You are also using a different model cooler on a different model cpu. Plus I didn't use as much of the AS5 that you apparently have. That can make a big difference.
