Q9550 Cooling Fan

I got a new PC 2 week's ago. It has a Q9550 it is overclocked to 3.4GHz. It has a Akasa AK 965 cooler that is what they gave. How do I check what temp my CPU is at? Do you think the Akasa AK 965 is ok?

Here is the spec of my PC.

Antec Nine Hundred Ultimate Gaming Case
Intel Core 2 Quad Q9550 overclocked to 3.4GHz
Akasa AK 965 cooler
Asus P5Q Deluxe Motherboard
Corsair 4GB DDR2 Ram
Nvidia Geforce GTX 280
500GB HDD
Thermaltake High Performance 850W PSU
Microsoft Windows Vista Home Premium 64-Bit
 
Its a decent middle of the pack heatsink if you have a adequate fan for it. 3.4Ghz is a pretty average OC from the Q9550 so you're ok there. Have you tried to push the OC higher and failed? You've obviously got premium components. If you wanted to spend like $80 on a HSF you could and you'd get one that cools a bit better.
 
Several programs are available Realtemp is as accurate as any and has a lot of features. It will show the temp for all 4 cores.

The way these programs work is that they read a value(s) from the CPU which is the distance in deg C to a value set at the factory called Tjmax which is the temp at which your CPU thinks it is hot and signals the motherboard to spin the cooling fan at 100%. Several deg C above this value the CPU will automatically shut down to save itself. So the proper setting of Tjmax in whatever software you use is what you need to check. For your CPU it should be 100C.

A personal comment, idle temps are for bragging rights once you are sure the heatsink is mounted correctly and all is well, to me what is important is the "delta to Tjmax" or in other words the number of deg C until the CPU thinks it is hot under full load with one of several stress testing programs available. If just testing the cooling Intel has a program that is a furnace, Thermal Analysis Tool and there is a newer version but do not have a link for you. Per the spec your cpu can operate 24x7 at 99C (1C to Tjmax) and be under warrany (the OC aside, that automatically voids the warranty but as it will shutdown due to overheating its not really an issue, just dont crank up the Vcore voltage too high) but most of us like to keep at least a 20C margin so 70C ish is a nice personal limit (20C to Tjmax) under full load.

I live in the UK, I ordered it from a company called Chillblast. They built and overclocked it.

That is a lot of info, thank's.
 
I was just on the internet not doing any gaming for any thing. Are the temps ok? I will take one after playing Crysis for 1 or 2 hours.

Looks fine for idle temp but doesnt tell the story for load. Try OCCT and set the custom time for 30 mins and run it. Keep Realtemp open and watch teh temp or check the maxtemp at the end.
 
My room is pretty warm today.

This is after playing Crysis for 40 mins.

Yeah, CPU's cool down fairly quickly so after temp wouldnt help. you need to watch temp during activity or keep realtemp open while playing. Even then its not going to reach the same temps as say encoding a video in handbrake.

Thank's.
 
All the fans are on the lowest settings and the fan at the back is not working. I am getting a new one sent out to me. :)
