Today I managed to get my hands on a new Intel Q9450 and upgraded from my old Q6600.
I'm a little concerned at the idle temp of my Q9450.
I'm using a Zalman 9700NT pure copper cooler my average idle temp for my Q6600 running at a stock speed of 2.4Ghz was ranging from 30 to 34.
I assumed with the Q9450 that considering that it is based on 45nm wafer that it would run cooler therefore my idle temps would be lower that what I was achieving with my Q6600 but my current idle temp for the Q9450 ranges from 38 to 40.
Check the fan fitting. I bent my fan pins to make the seal a little tighter. Then my temperature went down 10c. Also make sure you use enough thermal paste.
40c idle isn't bad anyway and I am sure your Zalman is plenty good enough.
I was gonna buy a q9300 today but I opted for the E8400 because it was a lot cheaper in price $212.00 compared to $299.00 at Frys, both with the same cache 6mb plus its 3.0GHz also . If they would have had the Intel Q9450 for $299.00 with 12mb cache then it would have been worth it, but I know it was like $549.00 and out of stock. Too bad im not a millionaire, but hey if you got the money why not right. How much did you end up paying for it, I figure close to $400.00 bucks.
