Firstly I do realise there are previous posts about this ; I just wanted to ask one specfic question and get some advice.
My desktop - The CPU, when rendering in the current (hot!) climate is around 57c
I have a core2 6700
Is this normal?
(It's 45c when Idle...)
Thanks for your advice in advance...
Hi,
Not sure what setup you are using but in most cases stock cpu fans that come with a system aren't always the best for cooling under stressful situations such as rendering with TG where it uses 100 % cpu. It's a good idea to blow the dust out of the cpu fans heatsink regularly for max cooling efficiency. Also if you are mechanically inclined a more efficient cooling fan replacement is hardly ever a bad investment for cooling your cpu and longer cpu life. Zalman is my pick. http://www.newegg.com/Product/Product.aspx?Item=N82E16835118223 (http://www.newegg.com/Product/Product.aspx?Item=N82E16835118223)
Below is a screenshot of my cpu temp while running idle. When rendering it runs around 43c. Just to give you an idea.
Well I have a Zalman Titanium so i'm even more worried now...I've also cleaned it for dust loads - the fan that is.
I wonder...?
I should also add, at times when my computer was in a hot environment and I couldn't afford a new cpu fan I just removed the side cover of my case and set a fan nearby blowing air towards the opening to help with circulation.
Thats the fan I have!! ::)
Is that the area you clean for dust or can you clean deeper???
RutRoh! Hmmmm? Are you overclocked? Or have you checked what the voltage for your cpu should be? Sounds like a candidate for water cooling if you are loaded with money.
I dont think I am over clocked - the CPU says 1.29 / 1.30 volts??

Sounds like you already may know as much or more than myself, as the geeks we are. ;) can't clean much deeper that the heatsink can you. I'm assuming the fan has good contact with the cpu and you properly applied good silver thermal paste?
When you say the heatsink - do you mean the blades of the fan???
Or do I need to take the fan off to clean the heatsink (something i've never done!)
(Thanks for your help Buzz :))
The copper fins of the heatsink not the (fan blades) can become clogged with dust preventing good air flow pulling heat off the cpu. If you run out and get some canned air with a extension you can reach into the heatsink and blow the dust out. You don't really need to remove it from your machine to blow it out. Unless you want to reapply the thermal paste. However you may want to take your computer to the garage or outside to give it a good dusting. Don't forget to blow out the power supply as it can also overheat. Try not to touch anything in the computer unless you are grounded or you may create some static electricity and fry your machine.
Thanks again - I'm on ebay now for some of that canned air!!
Cheers

ebay? Hell go to wal*mart in the electronics section. :D
As a Mac user, heat is nothing new to me. My iMac will easily get up to 70 when rendering before the fans kick in, but that's normal. I usually keep my fans going a little faster than normal, especially my HDD fan (for some reason, HDD's run very hot on these computers, and hot HDD's are not happy). When rendering on Mac Pro's, I find the temp usually doesn't go above 45, but that's because the Mac Pro I've used is liquid cooled (which is awesome).
Honestly though, I've never had any trouble with CPU heat, even back in my PC days. It's the HDD enclosure that's always made me nervous.. I've blown at least 4 HDD's, all from heat-death :(
As others have mentioned, getting dust out of there can help tremendously. If you're in a hot climate, that can always cause increases in heat too. Here in the Canadian climate, my computer tends to run a good 5 degrees warmer in the summer months than it does in the winter (when doing nothing intensive).
All kinds of fans are available at places like NewEgg and even Amazon, with reviews too.

Don't know if you noticed but the link I supplied is to newegg. I've done much research and this is one of the best fans out there. Or are you just posting to bump up your post total. ;)
What's the big deal with temperatures at 57 C?
I'd say it's very regular temperature when you're rendering.
I recommend getting Scythe Mugen. It'll allow you to overclock C2D up to 4GHz with reasonable temperatures.
Personally I like the Ultra Chill Tech for about $100.

Yes, I'm behind on my quota.
Sorry, I didn't see your NewEgg link. But...uh, I was reinforcing it. Sir. ;D

LOL ;D
I have AMD processors. Those get hotter than intel by standard. When the weather is hot my full rendering temperatures go to 60-68 C, depending on the pc. The slightly newer cpu is a bit cooler...
My laptop's CPU temperature gets up around 96°C when rendering or playing games or anything.

That's why I call the Laphots rather than Laptops. ;)
I bet that's like having a microwave oven open on your lap - probably not good for the gonads. And stuff.

Maybe that is the
core cpu temp rather than the bog standard cpu temp??
Hardware Monitor (Google it) will differentiate...
I'm using something like Hardware Monitor. The CPU and GPU Diode temp are basically the same. When I have both fans at 7000rpm and put the computer on an cooling platform with fans(using a modem power supply so they run super fast, and loud) the temp is only about 85C. The enclosure base sensor is only at 39C.

Hi, someone asked a similar question on the Bryce forums a little while back, here's the answer I gave which might be of help to you to:
"This might help you, it's from the forums of the company I bought my i7 PC from (I'd post just the link but you have to be registered to read their forums...) The posting is from the company's overclocking guru and it covers the temp's of the most common Intel processors...not sure what yours is? Where he says about running Prime95 I think you can safely substitute Bryce 6.1 running in High priority mode for the purpose of your concerns:
"The 2 main programs are Coretemp (Here: http://www.alcpu.com/CoreTemp/ ) and RealTemp (Here: http://www.techpowerup.com/realtemp/)
I recommend RealTemp for Intel Chips and CoreTemp for AMD Chips
Run the prgram, and if checking IDLE temps have no other programs running, and leave the PC for 10 mins without doing anything ad check temp - this is your IDLE temp
To check LOAD temp, run Prime95 Large In-Place FFT test for 30 mins, check temp. Ths is your LOAD temp.
These temps are what I'd expect on average, they are not completely set in stone and should be used as a guide only. Please read the whole post before panicking.
All temps are assumed to be using a Stock Cooler@stock speeds. If you have a better cooler expect better temps. Overclocked temperatures assume a V8 or better cooler is being used and temps are again not exact - expect a fluctuation of 5-10*C in either direction depending on your coverall cooling setup.
Bear in mind your case cooling has a large impact on cooling performance, if you have consistantly high temps and the steps at the end of this article do not help consider adding additonal case fans.
Intel Dual-Core C0/C1 Stepping

Intel Quad-Core C0/C1 Stepping
Idle Temps: 35*C-40*C
Load Temps: 40*C-70*C
Overclocked temp max: ~70*C
Intel Quad-Core E0 Stepping
Idle Temps: 25*C-35*C
Load Temps: 35*C-65*C
Overclocked temp max: ~70*C
Intel i7 Quad-Core C0 Stepping
Idel Temps: 35-45*C
Load Temps: 65-80*C
Overclocked temp max: ~75*C
THROTTLE Temps
When a CPU hits the temps listed here it will begin to trottle, effecting performance. If your CPU is hitting these temps follow the "what to check" advice in the next post.
Intel 65nm: 95*C
Intel 45nm: 85*C
Intel i7: 100*C
