I have an Antec P183 Case with an i7-920, Zalman 9900 and a Sapphire HD4890 no overclocking the idle temp according to PC Probe II is:

CPU = 45C - 46C
MB = 47C

The ambient temperature is 24.33C

The case fans are set at low and there is plenty of space around the case.

I am not a super experienced PC builder and wanted to see if this was normal.

The only thing I did not follow the instructions on was pointing the Zalman to the rear of the case and instead pointed it up...I thought it would make most sense seeing that the case has a fan right above it blowing out and heat rises.

I also installed an extra 120mm fan blowing air in across the hard drives.

I look forward to hearing your comments so I can hopefully sleep well at night.

Thanks,

Mitch

I have Antec 900 cases. I do the same thing. I figure that warm air wants to rise. Why fight physics. :) 

Idle temps seem a little high. What are your load temps?

Also, download RealTemp and use it for a second opinion.

And make sure that your HSF is properly installed.

Using RealTemp at 99.2% Load I got:

65C - 63C - 63C - 62C

I also cleaned of the CPU and Heatsink and reapplied the thermal paste because the guy who helped build the PC applied way too much.

At idle according to RealTemp I am at:

39C - 35C - 38C - 36C

I think this looks much better.

Thanks!
