Yeah the fans are great. I have them all on high as i am not sure what temp it is inside the case (any free utilities?) but the air coming out the back is freezing lol. The Coolermaster V8 CPU cooler is MASSIVE! It fills the entire width of the 902 case.

Very impressed with this system and despite the 2 crashes i had on the first day, which must have been Steam as it's never happened since, has run perfectly.

Speedfan can monitor your GPU, CPU, mobo chipsets and hard drives temps and can also control some of the fans too.

Mace, not sure how bad your processor and HD is, but my i7-860 with the cool running SSD remains at 5 to 10°C above room temperature, GFX remains under 50 most of the time. And that with the case fans on low.

These are really some of the best temperatures I've ever seen, so running your case on high might be noise overkill.

I just set them on high to make it the coolest without really knowing what temp it is inside the case. I have just installed Speedfan and all 4 cores are below 38C then I have TEMP 1, 2 and 3 which are no gigher than 45C (lowest is 26C which is TEMP 1) any idea what they correspond to?

Sign up for the Speedfan beta. You have to register to get to the download. Download it and all you have to do is take the executable that's in the download and overwrite the executable in the folder where Speedfan is installed. Make sure Speedfan is not running when you do this.

From what I've read, my board shows IT8718F three times and three different temps. I gather these are sensors in the mobo that monitor temps and control the fans if you have the mobo set up to control the fans. From several forums, the last one, which is always the lowest, can be disregarded and is a glitch of some sort.

Speedfan shows my temps as..

GPU: 48C vid card

Temp1: 30C mobo sensor

Temp2: 32C mobo sensor

Temp3: 25C disregard..glitch

HD0: 31C C drive

HD1: 32C D drive

Temp1: 40C northbridge

Core0: 39C CPU

Core1: 39C CPU

I'm seeing a "System" and a "CPU" Temp which are always the same, and idle at 25 to 30°C (25 is hard to believe, that's my room temperature).

I'm seeing an "AUX" at 37°C idle which I figure is the GFX card.

And last of all I have six Cores (Core0 to Core5) somewhere around 16 to 17, these must be wrong since that is cooler than ambient.

I recon as long as nothing goes over 60 underload I'm well in safe territory.

EDIT: Testing ASUS PC Probe, that one shows the same values as I see directly in my BIOS.

But there must be errors, since 20°C for the CPU, 30°C for the Motherboard is unbelivable.

There is always Core Temp. It used to regarded as more accurate than SpeedFan. Something about the way temps were calculated, but I think SpeedFan has implemented the same calculations. I ran them side by side recently and they were the same, now.

A couple of years ago though, Core Temp would show much higher temps. It works on AMD too.

Ah, the little useless things you pick up in your quest for overclocking nirvana.

Then, if you want really try out your new overclocked wonder, try out Prime95. It will submit your deathstar rig to the ultimate test, maxing out all cores and memory at the same time. That is how I found my maximum stable overclock of 3.8Ghz. Anything over 3.8GHz would either bluescreen or just lockup. You can watch your temps max out in real time. Pretty useful for seeing if your cooling solution is going to hang in there when the going gets tough. Also very useful to see if you need to back off on the Vcore a little before your proc goes up in a puff of smoke.

Thanks for the additional pointers, but I think my low temperatures are actually the way Intel does it. I seem to remember a while ago reading an article that said the intel temperature reports where always on the low side, hardware-wise already - not dependent on the software used to read the probes.

I uninstalled Speed Fan as my PC crashed after i had installed it and after uninstalling it hasn't... Seems to be very 'sensitive' to what is installed, is that W7?

One feature i do like in W7 is when I installed a version of Kaspersky W7 obviuosly didn't support because my PC would not start up past the BIOS screen so W7 kicked in and asked if I wanted to run a scan. it did so, found the problem, sorted it and it restarted fine. With XP I would have to restart in safe mode and try and figure out myself what the problem was.

Lesson learned - make sure I know software is for W7! I keep forgetting lol.

One question though, I left my PC on downloading something the other day and when I came home from work the PC looked as though it was shut down, fans off etc. but when I pressed the power button it came on immediately and the download had paused but W7 was still running, it didn't ave to start up. I am guessing this is an energy savig feature? If so how can I turn it off?

Speedfan (which I also had on the XP box for two years) has never caused me problems... it does seem to install some kind of system driver but if it's off, it shouldn't interfere with anything.

Yes, one of the new Win7 features (more like "process") is that when something unusual happens, it will offer to look trough known solutions. For example if you deactivate your speakers in the Audio panel, and then go to Maintainance Center asking why you can't hear soumd, Windows will correctly find that the speakers have been disabled. Of course that's a basic example, but shows how it works.

The mode you descripe sounds like hypernating (suspended to RAM), the energy saving features are one click away from where you set a screensaver, or in the system control panel. That was one of the last things I checked before finishing my upgrade, but my shop must have set that alright.
