45-46C good temps for 1.4GHz athlon using MC462-A?

[TonyB]

I got a 1.4Gigahertz Athlon running 45-47C using a swiftech MC-462A heat sink and sanyo denki fan that came with it, also using ASII. Are those temps alright, or can they be better, i see some people here reporting less than 40C, so im kinda concerned that my HSF may be defective or something. According to ASUS probe, my motherboard temps are 30-33C, so i guess thats my Ambient although my room doesnt seem to be that hot, maybe its just my case.

Don't know about others.. but my temp is 45-48C for CPU and 30-33C for Mobo. This is with GlobalWin WBK38 (I call it hair drier) with ASII and a desk fan blowing directly into the open case. I don't have a clue how others bring down the temp so much. As it is, WBK38 is driving me nutz with the noise.

Ur temp is OK.

Sanz...u r right....GW WBK38 is not a bad HSF but just noisy. I owned one.

TonyB, your temp is quite ok as your motherboard is also quite hot. I think the reason is that your place is a little bit too hot.

At first glance it looks poor for that cooler, however the Asus senors give higher readings usually.

My case has 1 intake fan slot in the bottom front of the case, the case cover is covering the fan, but there are vent holes. Lets say if I added a higher power 80mm fan to replace my old one will it increase my inside case temps and therefore lowering my overall CPU temps?

hmm, when I first installed my tbird 1.4ghz with a sk6/delta combo, I was gettting getting temps in the 44c - 49c range during idle. :frown:

So I searched around the web and found some different articles that talk about lower cpu idle temps

The article is on overclockers.com and is titled something like amd air conditioning. I would provide a link, but thier site seems to be down right now.

It involves using wpcredit and setting some different values.

After making the changes, I saw my idle temp drop to 25c! :Q

I think what WPCRSET is doing is enabling the chips HALT command. This lowers idle temps but does not lower load temps since HALT is not used during load anyway. However this can cause system instabilty on some systems. The reason for this is some powersupplies cannot handle the quick changing power demands between HALT and normal chip operation.

the following was grabed from Paul's unofficial FAQ for the KT7 (my board) @ www.viahardware.com:




<< Why is my idle temperature so much higher under BIOS version 3R or later?

With previous BIOS versions ABIT set a bit in the BIOS CMOS (offset 52 bit 7) to &quot;1&quot; to enable the ACPI &quot;HALT&quot; function and cool down the CPU temp in idle mode. This, whilst allowing cooler CPU operation, is against the advice of AMD and VIA. Under earlier AMD processors, however, this modification allowed the system to idle cooler and had no ill effects. However, it was been found with newer 133MHz FSB processors running at 1333MHz and higher, that this software cooling can cause severe stability problems - especially under Windows 2000. As a consequence, in all ABIT BIOS releases after version 3R, ABIT have set this bit to &quot;0&quot; - the value recommended by AMD and VIA. This allows the motherboard to be stable with all AMD processors at the expense of an increase of 5-10 degrees Centigrade during idle (from approximately 35 degs C to 45 degs C). This will not harm your motherboard or processor. Note that this CMOS setting is widely used by other KT133/KT133A based motherboards. Note that if your processor is slower than 1333MHz then you can revert to the previous setting of the BIOS by using H-Oda's WCPREDIT and WCPRSET programs to modify this register value. If you are using Hex mode in these programs then change register 52 from 6B to EB to re-enable the software cooling.

He explains somewhere else about the powersupply being the cause of the instability. If your using a good powersupply this probably won't affect you.
In any case I recommend you look into the specifics of your MB before making any mods to the bios registers.

TonyB, what's your ambient room temperature? You also wanna make sure you have the heatsink on securely, i.e. screwing down the heatsink screws until they bottom out. You should be ok if you installed it correctly.........
