I didn't know where to go to ask this question. So I apologize, and hope I am in the right place. I had a curious question about my mobo NB temp. AT idle its hot at 65 degrees. But, when under full load... say when i'm playing a demanding video game lik battlefield 3, my NB temp then goes down to under 55 degrees. is this normal... or is it possibly a sign my psu is going bad? undervolting protection is bad?
at first i thought maybe the program was was reading the temperature settings incorrectly, but i tried hwomonitor and a couple others....all said the same. and so i did the finger test. and to my amazment......the heatsink on the NB is much cooller to the touch when the pc is at full load. does this make sense?
all my other temps are fine. this is the only weird one. my gpu is at 75 at full load. cpu cores are 50 at full load. basic stock cooling. socket temp is ok. Is this normal for these newer mobos? maybe by design.?
I have a dell studio xps 7100. which supposedly has a custom gigabyte mobo.
amd phenom II x4 820 2.8gz
6b ddr3 1066
ati hd 5870 1gb
win 7 64bit
i've been thinking i need a new psu because the fan is starting to make alot of noise at times and is running really hot when stressed. its a little over 2 years old. and is a cheap crappy stock dell 450 watt. I'm also starting to get cpu spikes after playing bf3 after a while, maybe this is due to the psu? Jjust by touching the grate at the back of the case i notice the psu fan is not blowing air out enough and is extremely hot to the touch. So i think i should replace it asap. so when checking my pc i just noticed the strange NB temp. i do sometimes hear a very slight coil whining when the cpu idles down after very heavy stress. should i shut off amd cool n quiet in the bios until i get a new psu? or is this not an issue?
any thoughts on this? I'm a noob so i apologize if these are dumb questions. ty in advance fo your patience and understanding.
EDIT: also is this a good psu to get? http://microcenter.c...TX_Power_Supply Microcenter is close to me and i prefer to buy one there. ty again for your time.
