Alpha 8045 Temps high - Help/Ideas?!?

[Mithrander]

I just recently bought the alpha heatsink with a Panaflo L1A80mm fan. Been running it on the following system:

AMD XP 1600+ at 140fsb (~1700)
Samsung 512 PC2100 DDR RAM
Gainward GeForce2 Ti450 64mb Golden Sample
Epox 8KHA+ mb
Sparkle 350w power supply
SB Live!
Evercase E4252 case

When I first boot up, temps are around 29 degrees C, but it steadily climbs to 41C before it somewhat stabilizes. I'm using a layer of Artic Silver II paste, so that shouldn't be the problem. The only oddity is that I forgot to install the intake cover between the fan and the heatsink (I'll get to it as soon as I find a small enough screwdriver), but I don't think that should cause the temperature to jump so much. On a side note, there was a thin yellowish layer on the bottom of my Alpha 8045. I initially thought it was a sticker, but it seemed stuck on pretty tightly, so I didn't take it off and just spread the ASII over it. Should I have taken it off first?

Here's my voltage readings using MBM5 for my sparkle 350w:
(They also seem to be a bit low, so any comments on these readings would be greatly appreciated)
CPU Temp: 41¢ªC
Case Temp: 31¢ªC

(All averages)
Core 0: 1.79 V
Core 1: 0.00 V
+3.3: 1.50 V
+5.00: 4.87 V
+12.00: 11.62 V
-12.00: 1.91V
-5.00 : .54 V

Most of the posts for the alpha seem to have temps hovering around 35-45¢ªc. However, I replaced my FOP32-1 HS with the Alpha, and the FOP32 was giving me a temp of 37 to 40¢ªc.

I have a hard time believing the FOP32 is a better cooler, especially since the noise level of the Alpha really isn't that much quieter.

Any ideas?

There is nothing wrong with 41C with a case temp of 31C.

you aren't talking about the copper in the base, are you?

Alpha does put a layer of some petroleum jelly-like substance on the bottom of their copper heatsinks to prevent oxidation. You need to clean this off before installing the heatsink.

I just upgraded to a 8045 too from my 6035. Your temps seem quite reasonable. I run around ~50 C on my Athlon 1300. However I have an A7V133 which typically reads temps higher than other boards.

Thanks for the replies. The yellowish part is apparently the copper base after all and not to be tampered with.

Seems my temps are normal to what others are having - guess I had higher expectations from it (was hoping 25-35C range).

Your room temp also plays a role.

Asking people "What temp is your CPU running at?" will get you an answer as honest as "How long is your uhhhh..... unit?"

Most people either mismeasure, misinterpert, or downright lie about their reported temperatures. You are just fine at 41C.

What Windogg said. Actually, I think those are amazing temperatures considering the Panaflos don't move much air.

Yeah your temps are not high especially with the panaflo. My 1800XP is 35 degrees idle and 38 degrees C under stress with the 8045 coupled with a 40cfm Sunon fan. Case temp is 25 degrees C.

Let's look at the key number.

CPU Temp - System Temp = 10C.

Your running 10C over system temp. I'd say your temps are nowhere too high.

Never thought about it that way, Windogg. 😀

For my next trick, I think I'll try replacing the fan in my Sparkle 350w - it's not too loud, but still not a "quiet" power supply.

Thanks for the answers, guys.

Your temperature is right for the fan you're using. I have an identical setup at home except I have a p4 1.6 at 133 FSB.
At idle, my room temp is 31 and my cpu is 32, which is good because I know the HSF is doing it's job. But at full load, the cpu temp rises to about 41 also.
This is because the fan isn't blowing enough air to cool your heatsink. This is the sacrafice you make for a quiet computer. I've placed other fans on my HS and have gotten lower temps, so I know it's the fan not blowing enough air.
