Hey guys, well during winter my PC was fine and dandy being quiet. Now its sumer in so cal, with system temperatures reaching 40C with all my fans at 12V. One intake 120mm Papst, 1 exauhst 120mm fan. Modded BQE PSU with a PAnaflo M1A, running at 12V. Thermalright SLK-947U. With a panaflo H1A. CPU temps are fine.. but idle at 40C just to hot in southern california. Now im getting random restarts and i think its the heat problem. Any ideas on what to do?? Thanks

I second CactusInvasion's comments.

err sorry 40C system temp. hehe woopsie. Well anyway I ran the mem test and it looks okay through 2 loops. Voltages seem to be a bit low though. 3.22 on the +3V. 11.8 on the +12V. 4.92V on the +5V.

None of those voltages are low. As long as they are always within 5% they are fine. That means 3.1~3.5, 4.75~5.25, and 11.4~12.6.

Esp as your board sensors may not be reading them correctly, they are absolutely nothing to be concerned about.

2 loops may not be enough. Try 24 hrs...

Also, what is your CPU temp at load?

The "system temp" is mostly meaningless, it's just some point on the board near the CPU, usually. If you want real system temp, the best point is about 1" from the intake of the CPU cooling fan. Or take a probe, move it all over the area counr the CPU, and see what kind of range you get. This requires the case to be closed and temps to be stabilized before reading. (ie, it's tedious)

CPU temp at load gets to about 50C. What sucks is its still relativley cool for summer here in southern california. Highs are only about 90F right now. Once August hits, temps touch 100F-110F... So Im not sure there is much I can do. No AC

50C is no big deal. 90F=32C; 110F=43C. The latter number is hard to believe... I'm down in the LA/SF area often enough, I don't recall temsp THAT high. Anyway, if your temps went up by 10C, your CPU would still be only 60C. Still safe.

Random reboots are another thing...

Hate to break it to you bro, but he's 100% correct.


BTW- Keitaro - Not that my rig is particularly similar to yours, but it's 88°F inside my house right now and my system (system #1 in my sig) is idling at a CPU temp of 38-40°C, sytem temp of 35°C and tops out under full load around 55°C under these sort of ambient conditions. Your temps are perfectly fine and I sure wouldn't worry about them, you're not even close to running too hot. Enjoy the silence. Right now, for me, the loudest thing in the house is the sound of the sweat drops hitting the keyboard!

RH, I defer to your local knowledge. But man am I glad I don't live there! 43C is as bad as Bangkok! No wonder you have to be up at 4am to test HS!

hehe alright, i stabalised the problem a bit. Underclocked some and its stable for now. Thanks guys. So when should i start worrying realy worrying about temps? At least system wise.

Man I feel bad for people who don't have AC, you can't get as high an OC. I don't know much bout where you live in CA but in the parts I've been to it gets cold at night so if you want to run your rig full speed you should become nocturnal.

SF hit 90F maybe once during the 4 years I lived there. LA hasn't broken 90F more than a couple of times since I've gotten here. However, 20-30 miles away from me (Santa Monica) it hits 110F on a regular basis during the summer. They keep insisting it's called the valley, even though the real valley (Silicon Valley) is back up near SF.

All you can really do when it gets hot is to scale back your system. If you can run on one HD instead of 2, unplug one. If you're overclocking your CPU, stop.

here we go, this sounds fimmiliar a bit (search for my handle) have a look at the power supply. my cheapo 500 gives me minus 15% on all rails, overclocked 20% at full load, 60C ~141F
normally clocked with AC on at idle i run about 113-116F things have improved alot with the addition of a spare 200W to handle the molex and fans. , and i still cant OC that much better...hope this helps.
