I need help!!! zalman cnps7700, arctic silver 5

is this normal, is there a break in period for the as5 to spread and do it's stuff? i spread a thin layer over the cpu as instructed. only thing was that the back plate of my mobo did not come off so i used it instead of the one supplied but it installed well and it is pretty snug with the cpu (my mobo id the asus k8n-e deluxe, my cpu is the amd athlon 64 3400 754).

as i write this the temps are starting to drop. it is currently at 56c at full load.
 
I only "know from AMD" based on what I've read on this and other forums. The last AMD CPU I purchased was a replacement for the Intel 8088. But what I know and what I've read, lead me to conclude that a load temperature of 56C is not excessive for an AMD system under full load.

Still, you would expect more from a Zalman CNPS-7700-Cu, I suppose . . . .

Figure it takes about 200 hours (so I've heard) for AS-5 to "cure". That's around eight days of constant running, but I also heard that it cures faster if you shut the computer off, let it cool, and start it up again -- several times over at least part of those hours.

Still, I have to classify this advice as "folklore" . . . . "Ah heard it through the grape . . . vine . . . "

You never mentioned whether you have your system configured to an over-clocked setting . . . .
 
I installed a Thermalright SLK-948U with a Panaflo H1 92mm fan on my Athlon64 3400+ (754 pin) last night and depending on how I set the bios is what kind of temps I see. If I use the cool and quiet, with the lowest CPU temp target, I see a full load spike of 50C with it usually around 40-45C. Idle temps are in the mid 30's. If I disable the cool and quiet and CPU target temp, I see idle temps of 30C, otherwise my idle temp is about 35C. So, with it as quiet as possible, I can see about a 10-15C spread between idle and full load temps. With the sound all the way up, I see about the same spread, with the temps starting at 30C...

My next mission is going to be to find a cooler, or method that will be virtually silent, but allowing for better processor cooling. I did use the AS ceramic compound on my rig last night for the install... Which might have something to do with the temps...
 
Have you tried removing it and checking to see that you had made good contact with the cpu/heatsink? I know you'll have to start your break in period all over again but you mentioned in another thread that this temp is 4c higher than the stock cooler, which doesn't sound right. Also doesn't the Zalman come with a fan speed controller? What is it set on? high/low/medium?

AS ceramiqué is what I use. Its much easier to clean than AS5. I use a Panaflo M1BX (has rpm monitoring) and its quieter than the H series, but still "noisy" to me @ 7V. Kinda wished I sprang for the 92mm L1. Even though I have an AXP OCd' for reference when my BX fan is set to 7V, i get around 45-55C Idle to load with 60F room temp. At 12V, I get around 37C-43C idle to load. (Heatsink is SLK-947U)
 
I found it neccesary to use the included backplate with my zalman cooler to get full contact. The normal AMD one just isn't designed for it.

I did the same thing with my Thermalright cooler... I wasn't about to mickey-mouse up the backplate from the stock cooler... It was a bit of work to get the factory plate off, but at least I know that the one on there now is the one that's meant to be on it...
 
two days later my load temps are 50c and 35c idle. it seems to be dropping daily. it still is in the realm of stock hsf numbers though. i just added an arctic-cooling silencer 4 for my x800 pro.

another thing i have to factor is that though it is winter my apartment is very hot. it is very likley that a couple of degrees are attributable to that factor. i will wait a week and if i don't see a significant change, i will go through the ardeous task of doing it again.

:Q No wonder you're having cooling problems.



You could also lower your CPU's stock voltage (1.50V) a bit assuming you're not overclocking. That'll lower it a few C's more.

e.g. my A64 errors @ 1.30V under Prime95 and passes @ 1.325V*. So to keep it stable with enough voltage @ a margin I'm comfortable with. I operate my CPU @ 1.4V which takes off between 6-8 C's (dependent on ambient temps) from temps I'd normally get with stock voltage. I assume another benefit from running with a lower voltage is the delaying effect against electro migration.
