Hey,
I have just upgraded my PSU from a crappy generic one to a £60 Antec True Power 430W PSU as my computer could not do anything without rebooting as it needed too much power.
The new PSU is great - much quieter and rails seem to be better - apart from one - the +12v is always 11.7/11.8 and everything else is just about right. When my PC is at full load it has rebooted a couple of times - I didn't think this would happen any more with my new expensive PSU.
Also, my CPU is getting very hot! It's at 62C now just listening to music and typing this and I have 7 fans in my case! When the case side is off it drops right down to 50C.
What could be done to lower temp and why is +12v so low?
Thanks in advance!!
Josh
7 fans is overkill. If your CPU temp is even lower with the side panel off, it sounds like you have them configured wrong. In most cases, a front intake fan & rear exhaust fan, along with a dual fan PSU are all that's needed. Since warm air rises, a top "blow hole" exhaust fan usually works well too, but side panel fans disrupt the front to rear airflow.
Is your heatsink installed properly?

your rebooting problem is due to overheating, not your psu

i agree.
12v prob is ok, there is no prob there.
I would say its a heat prob as well.and all u need is 3 fans.
2 80 mm case fans, 1 in front, 1 in rear, and a fan on CPU.

also, tuck all cables off to the sides off your case
and dust thoroughly once a month
and check regularly for fan failure, it happenswhat is painfully obvious to one person might be just painful to the other

Thanks for advice. Why would the computer automatically shut down at around 60C though? I have checked all BIOS settings and it is set to shut down at 90C - so why 60C? I have a dual fan Antec True Power PSU, a huge Coolmaster fan on my CPU, and then there is one on M/B and one on graphics card as well as one on the side of case to get rid of hot air. I thought this was a good set up? I am still getting shut downs under full load. I then have to turn the PSU off by the switch and then back on for the computer to boot up. It will not boot until I turn PSU off and back on. I have ordered some Artic Silver 5 stuff - will that help?
Thanks very much

"I then have to turn the PSU off by the switch and then back on for the computer to boot up."
this is a difficult problem to diagnose
duh
i have heard of this before being caused by a conflict with the psu and the mobo
but this was in a magazine and it said that that was a fix in one of the cases
it could also be that the outlet on your wall is not pumping enough juice
it should be 120volts
or your surge protector could be acting up
you never knowand dont assume that just because this psu is brand new that it is fully working
it could be going bad as we speak that is the unfortunate truth when working with computers
"there are two kinds of hardware, those that are failing and those that are about to fail"there could also be a componet going bad or just screwing up while you use your computer
also you say that you have seven fans
7 fans IS too many
6 is pushing it
if your cpu heatsink/fan is great but your temps are still high then you should check to see whether or not you installed it correctly"Is your heatsink installed properly?"
