Zalman + CPU = hang :(
Just a few hours ago, I installed the Zalman 7000 heatsink. I removed the thermal paste from the CPU with some rubbing alcohol and then later applied a bit of arctic silver 5. I attached the Zalman, attempted to boot...hard drive spins up and stops, and it hangs. I put a bit much arctic on, maybe 25% too much, but I’m wondering why this would do anything... Nonetheless, this seems like either a CPU failure or my motherboard is not liking the low RPM of the Zalman. Any help please...i hope i didn't lose this $270 chip.

Alright, a follow up. I removed the heatsink and processor, and they bothed showed the expected (normal) amount of thermal goo. What the hell is going on here? Maybe the chip was damaged, or the heatsink is weighing too heavily against it? I'm really at a loss.

Are you sure you don't have a bit of "goo" on the chip anywhere (or on other components around it) that might be causing a short? Also, if you had to take the chip out of the socket, take a look at the pins on the cpu. I hate to even think about bent cpu pins but... yuck!! Also make sure your new Zalman is plugged into the mobo nice and solid.

Zalman is plugged in solid, and the pins are all fine. I did check for goo around the components, and it seems to be absent. *confused*
I guess i'll just try reapplying the paste. Does anyone know how many times is the "limit" for removing/reapplying this stuff? |

No limit. Just make sure everything is clean. Only use a thin layer applied to the core of the cpu. Use a thin plastic applicator like a credit card to spread the AS5 thin. Here's a link to the correct way to apply:

It would help if you gave us the system specs and the exact model of the Zalman you're using.

All good stuff except for the one mostly likely causing the problem - that Allied Power Supply. One of the brands most often recommended for replacement due to poor quality power output. See where it ranks here:

Yeah, I know. In retrospect that was the only thing I regretted buying...and am still considering replacing if it's too loud.

Are you sure the Zalman is installed properly? Is it making full contact with the heat spreader on the P4? The attachment system for the Zalman's have been known to confuse the user and they find the heatsink isn't making good contact with the CPU. The heatsink has to make full contact with the heat spreader and it should have lots of downward pressure put on it by the screws.

Ok, it's all better now. I'm not exactly sure what happened, but removing and putting back the CPU seemed to be the fix. That sure was a _long_ process. I guess most of the time was eaten up trying to get off the original heatsink - a pain in the ass that might be minimized in the future now that i've done it. Installing the Zalman itself, and the thermal compound, wasn't too difficult at all.
One final question: I'm a bit worried about the way I applied the paste. I noticed some of the previous paste went off the edge of the CPU, and was hanging on the sides (it didn't actually touch the green part of the P4, but was too close to it for me to risk using rubbing alcohol to get it off). So, will that be a problem, and, secondly: I again put the stuff a little close to the edge, and am wondering if this is going to seep off onto the edge and possibly cause any issues? By the way, the PC runs quieter and cooler now...yay! The power supply, in addition to being an apparent piece of crap, is now the loudest component in my system. |
