miami's too hot! What's too hot for CPU temp?

My PC's been acting really strange lately, mostly with sudden freezes. I see that things start running smoothly after a while, so I'm guessing it's a heat issue, because otherwise the machine's been running fine for basically forever.

I checked the CPU temp in the BIOS, and it was 77 celsius. I read somewhere that 80 was where the motherboard would automatically shut down. Well, I'm guessing that that's the problem.. Can someone varify that 77c is too high?

It's probably the heat in Miami. Or my water cooling system may be malfunctioning.

man.. is it just the heat or what.. maybe I have a broken CPU fan. My CPU temp goes from 30 (after a while of no use) to 70 in about an hour. And that hour was spent constantly compiling flash movies. Which shouldn't be a problem considering I've done 3D graphics renderings that lasted for days.

I just downloaded motherboard monitor, and set an alarm on 70 degrees celsius... but isn't this heat up kind of fast? Considering I've never had this problem?

and the sad part is that I have a water cooled CPU system that I got in Japan, and I live in Miami right now. Darn.

Maybe you are right, there is a problem with your cooling.
A graphic card can get real hot and maybe it influences the sensors of your mobo sensors additional to your CPU.

A while back I had the same problem, in heavy duty the CPU reached up to 80 and more celsius. Around 40 normal.
I bought a new graphic card and a new CPU cooler. Now everything is fine.

Maybe an additonal cooler inside the case can help too, hardrives, my SATA for example produces heat too.

Easy enough to check, just whip the case off and turn it on!

Do you have room for any additional case fans? They might help keep things cooler.

same here, but it's bloody cold outside, 5 celsius or so.
in my case the PSU sits too close to the CPU so there's not enough temperature difference under heavy load.

the monitor now shows 25/33 but it will rush up to 70 within a few minutes if I send it into a closed loop.
once it climbs beeyond 76 the PC will become rather strange then.
my case is open and I verfied the temperature by touching the cooler - it's not a mistake, it feels insanely hot in those cases...

cheers, tom

Hi Ken, as far as I know, it's recommended to clean out your water cooling system. Depends what type it is I suppose, but the one I had & others I've read about need to be cleaned out quite frequently to continue getting decent results. Mucky oxidation & tiny metal fragments etc will gather in the water over time. Combine that with the cheap (rip off) cooling fluids normally used & what you end up with after a few months is closer to slime flowing around in there. Take it all apart & clean everything as well as you can (including flushing the tubes etc) It's a pain (main reason for ditching mine), but you'll definately notice a difference after cleaning it all out & refilling with fresh water & coolant

The other thing that can happen if you use a pump, is that they can overheat if either badly needing a filter change or obviously if it's faulty. When the pump overheats it will heat up the cooling liquid it's pumping, which is not good (hence low power pumps are recommended for water-cooling).

Stick your hand on the pump. It shouldn't be roasting hot.

hmm... I'm writing the makers of the water cooling system in Japan, but they're not much of a help. I'm planning on ditching the system all together, and replacing it with the good ol' fan system. I can't be letting my system cool off every hour. Well, it gives me a good coffee break tho.

I'm asking whether I can just take out the water cooling system because I don't want to have crap leaking all over my MB.

What system is it?
I'd normally just power off, disconnect the mains lead, then remove the CPU & GPU blocks intact along with the rest of the WC system, without disconnecting a single barb. As you say, you don't want leakage & the easiest way to not have leakage is to take it all out intact.

Thnaks for the tip shrooms, I'm going to have a go at the CPU fans today. I needed to replace a couple of hard drives anyway. Wish me luck guys, and hopefully I can get this sorted out and finish my project in time!
