DJDeez Posted September 10, 2005 Share Posted September 10, 2005 Hey all, Just recently got a Zalman CNPS 7000 B - CU cpu cooler, it replaced my Spire Whisper Rock IV. I've got an AMD A socket (Athlon XP 3000+ ~ 2.17ghz). I mounted it into the case, applied thermal grease, and started using it. However, when I check my BIOS, it says that my cpu reaches a temperature of 51 degrees Celcius. How can this be? Did the temperature sensor go mad or something? I'd expect the cpu to be around 35 degrees. Thanks for any help. Link to comment Share on other sites More sharing options...
vALKYR Posted September 10, 2005 Share Posted September 10, 2005 How did you apply the thermal grease? Link to comment Share on other sites More sharing options...
DJDeez Posted September 10, 2005 Author Share Posted September 10, 2005 I put a thin layer on the processor where it makes contact with the cpu cooler, like it said in the construction manual. Also, when I start the computer, the BIOS says the temperature of my cpu is 40 degrees. Link to comment Share on other sites More sharing options...
vALKYR Posted September 10, 2005 Share Posted September 10, 2005 When I start it it's around the 45-50°C. Then after loading Windows and logging on it's 45°C (with 29°C Room Temperature ) Like you said, I tried that first, too but got 55-60°C after loading Windows so I just put the grease on but didn't rub it out. Then I put on the cooler, put some pressure on it and bingo: 45°C at starting. Link to comment Share on other sites More sharing options...
DJDeez Posted September 10, 2005 Author Share Posted September 10, 2005 Thin layer = lose? Hmm, I'll just put on the remainder of the grease I've got left then and we'll see what happens. Maybe the heat can be transported properly with more grease applied. Link to comment Share on other sites More sharing options...
vALKYR Posted September 10, 2005 Share Posted September 10, 2005 Well, if you put everything on it it's a lose also. Link to comment Share on other sites More sharing options...
DJDeez Posted September 10, 2005 Author Share Posted September 10, 2005 Grease turd applied, let's see what it does. But yeah, that's still not going to be close to the expect 35 degrees. I mean, what if I would've had an AMD 64 processor? Link to comment Share on other sites More sharing options...
Forfit Posted September 10, 2005 Share Posted September 10, 2005 Why does it seem like your guy's temps are cooler than mine? i dont get it, my computer runs idle at 54-55C Stock and now that i think of it that sounds blazing hot. and the fan only spins like 920RPM's Average. It's a AMD XP 3200+ @ 2.2Ghz it seems odd that your fan ould only be going 900RPM, and 55*C sounds extremely hot for stock clock speeds. the failing point for the XPs is apparently 70*C so as long as your temps stay under that, it isn't TOO much of an issue. the reason my temps are so much lower is because my processor is an athlon 64(which is going to be a little cooler) and because of the heatsink. at stock speeds, the heatsink was keeping the processor at about 25*C Idle. I have a xp 3200+ that runs about 54C idle and according to what Sip Yek Nod said in another topic....his AMD 64 runs cooler even when overclocked.

maelstrom Posted September 10, 2005 Share Posted September 10, 2005 I also have the 7000B cooler - on my A64 3400 it is 44c idle in the bios... I didn't use the fan controller, just directly to the motherboard header for full rpm's. Link to comment Share on other sites More sharing options...
DJDeez Posted September 10, 2005 Author Share Posted September 10, 2005 How much thermal grease did you use? After adding a lot more I got the temperature back from 51c to 48c. Link to comment Share on other sites More sharing options...
Wolf68k Posted September 10, 2005 Share Posted September 10, 2005 Did you use the thermal grease that came with the Zalman? If so go get some Arctic Silver 5 thermal compound, and be sure to read their web site which has detailed instructions and pretty pictures too on how to apply AS5. Read them top to bottom, print the pages out and read it some more, start to work and have the print out on hand and keep reading. Link to comment Share on other sites More sharing options...
SIP YEK NOD Posted September 10, 2005 Share Posted September 10, 2005 (edited) the atlon XP's naturally run at a higher temp. the "danger zone" for an XP is 90*C whereas the "danger zone" for an athlon 64 is only 60*C so 51*C is within the normal range, and if the heatsink was installed right, should be lower than your previous temps. you should be comparing to your previous temps, rather than the temperatures other people are getting with athlon 64s Edited September 10, 2005 by SIP YEK NOD Link to comment Share on other sites More sharing options...
DJDeez Posted September 11, 2005 Author Share Posted September 11, 2005 Thanks for the tip on the thermal grease wolf, I will read all of that very soon. I'm going to remove some of the thermal grease tomorrow, so only a thin layer remains. It's Zalman grease, yes, but maybe there's too much grease applied now, with all the different tips I got. If there's no difference tomorrow, I'll contemplate on getting some arctic silver. Thanks for the insight, Sip, that explains why the athlon 64 temperatures are a lot lower. I think I used to get around 56-58c using the old cooler and now I get around 48. Messing around with the grease a bit should get it down to 45 maybe. I'll post the results.

Wolf68k Posted September 11, 2005 Share Posted September 11, 2005 What is the room temp.? Link to comment Share on other sites More sharing options...
DJDeez Posted September 11, 2005 Author Share Posted September 11, 2005 (edited) The room temperature is around 27 degrees now and the mobo temperature is exactly 30 degrees. I whiped off all thermal grease and applied a very thin layer. Same result: 48c. Edit: AS5 ordered. Edited September 11, 2005 by DJDeez Link to comment Share on other sites More sharing options...
