I'm using the same processor and MB as yours. I have the same OC setting ( 333 x 10.5 = 3.49Ghz) as well because predictably I'm using 667mhz rams.
(I swap the stock cooler to after market coz my E7400 reached 96 Celsius when gaming. The max temps recommended by Intel is 74.1 C.)
BUT, the differences is in the temps. On load mine is max. 49 Celsius; on ilde is 30 Celsius. (load = Crysis on high settings)

I got myself Arctic Cooling Freezer Xtreme, market price @ RM200 but I bought it for only RM140 at C-zone sdn bhd. at Lowyat Plaza. (apparently their stocks of AC Freezer Xtreme are a little defected. So their selling it cheap. But for a cpu cooler, a little bent here and there is no big deal, mine I got a scratched top part and a bent little fin. with a good'old plyer, i fixed it like new less than 2 minutes)

My point is that, if you had an extra RM40 plus the money u bought the CMH TX2, u could have bought the AC Freezer Xtreme, for sure you can get kinda the same temps as mine since we both use the same Mobo, rams and proc with similar OC settings. Anyways your load temps and your idle temp ain't too bad, but still the temp could go down a little, especially if someday you decide to get 800mhz rams and push the Ghz of the proc up to 4.0Ghz

Hope you find this info useful from another E7400 user
