Hi peeps I need your help. I have just built a new PC which I was actually going to overclock on but I’ve hit my first hitch already and I’m only at the PC configuration stage in the bios.
Right, I installed all the hardware no problem, checked everything, wires as you do then I turned my PC on I went straight to the bios to check and configure all the settings as you do. I then went to "Hardware Monitor" to check my CPU Temp and MB Temp and it was at 42C/107.5F my case temp was around 33C, now I have a Scythe Ninja+fan cooling my 3700 SD CPU, I am pretty sure you shouldn't be getting these temps. I turned off my PC checked all the connections and heatsink just encase I f_cked up installing it then I turned the computer back on I then went to the bios> hardware monitor and watched it for 10/15 minutes. Their is definitely a quick temp rise on the CPU as it started at around 31C and rose to around 41C in about 15 minutes and steadied itself at around the 42C/105.5F mark I left my pc on for a further 2 hours in bios>hardware monitor, idle. Came back the temps seem to stay at 44C and didn't rise, that is concerning me considering I haven’t even put the CPU under any pressure yet and its idle'ing at 43/44C I’ve not tried to overclock or even install Windows XP yet. So the next step for me was to do it all again. I took the 3700 SD chip and heatsink out cleaned them with arcticlean remover and purifier, once cleaned put the Arctic Silver 5 back on the CPU. I done all the thermal silver 5 right as I followed Arctics silver guide, installed it again turned on the PC went to the bios> hardware monitor, SAME problem high temps. I cannot understand it where I am going wrong. The Scythe Ninja is new no marks, the AMD Athlon 3700 San Diego is retail brand new, Code ADA3700BNBOX, KACAE 0605 and I have a great case the Gigabyte Aurora all fans working fine. I do not know why they are so high or what to try next in the bios or in the case? I hope you experts can help me it would be much appreciated Az

Check the heatsink is seated properly.

I re-installed the heatsink twice now reading through the manual and double checking its seated properly it all seems fine. The only thing i didn't do with the Scythe Ninja was to put the backplate onto the back of the mboard i am using the backplate that comes with the mboard, which is fine i read as many people do that.
 
Testing the AMD supplied heatsink and its been in for around 15 minutes now and its at 38C/98.5F so it is slightly better but again 38 when its idle'ing is Bios is quite high isn't it?

the reason is, you are not idling in the bios, anytime that u are in the bios the cpu is underload, even if your not doing anything, im playing with my cpu again, and is on average 5-7c higher in the bios than in windows, try it in windows, you will be pleasently suprised
 
are u sure, heh heh if thats the case then i feel like a right dumb arse. I honestly thought the bios wouldn't put much pressure on the CPU at all. that my explain why my Ninja was at 42/44 then. One thing that still doesn't make sense though if thats the case then why was my standard retail amd heatsink and fan was running at a lower temp then the scythe ninja it was running at 39C and stayed at the temp. I will take my mboard off and put the scythe backplate on the mboard might help.

Try other software to check temp incase its wrong.

Sorry, how would that workabout? Thought that 'other software' gets temp readings from same place BIOS does?

Also, doesn't 'Arctic Silver 5' take sometime to be fully effective/settle in? Cos whenever I do a system clean-up and reapply the compound my temps are high for some days then start 2 come down.
 
Did they come down substantially... What was the temp drop? From what i have read people with similar specs and same ninja heatsink as me theirs seems to be at anything from 29C to 35C mine was at 44c would i see that sort of decrease do you think?
 
my opteron @ 2980mhz is 32c idle, so there's something wrong there.

to the op - i cant only suggest trying the proper backplate. maybe there isn't enough tention ther on the cpu to pull the HS tight :confused:
 
from here:
'Due to the unique shape and sizes of the particles in Arctic Silver's conductive matrix, it will take a up to 200 hours and several thermal cycles to achieve maximum particle to particle thermal conduction and for the heatsink to CPU interface to reach maximum conductivity. (This period will be longer in a system without a fan on the heatsink or with a low speed fan on the heatsink.) On systems measuring actual internal core temperatures via the CPU's internal diode, the measured temperature will often drop 2C to 5C over this "break-in" period. This break-in will occur during the normal use of the computer as long as the computer is turned off from time to time and the interface is allowed to cool to room temperature. Once the break-in is complete, the computer can be left on if desired.'

Yeah - I heard that the BIOS puts the CPU under load also... not too sure why - will have to investigate.

I assumed it's because the CPU is doing all the graphics work and not your graphics card.

no, its because the cpu isnt fed idle instrustion when in the bios so it doesnt shut down like it can in windows.

Thanks for clearing that up :)

I assume instrustion is a typo?
