Holy moly burebista! If I'm reading your ruler right that looks like about at least a 1-2 mm warpage (out of true). That would take serious grinding not lapping.

Jdrom's right, I have the same problem the average ambient air temperature in my place is no less 26-27oC pratically everyday of the year. Even with a true I have greatly higher idle temperatures on my Q9550 than most would even at stock.

Take the advice of most here add another fan, increase airflow, get bigger case, etc. all the those things are bound to help.

It's not mine, I have a good friend with a hobby: testing a lot of heatsinks vs. TRUE. Here you can see Copper, TRUE Black and HR-01.

I just replace my Ninja with Noctua NH-U12P. I'm lazy to lap and mod a TRUE.

Thanks for all the info, guys. I'm planning on watercooling soon, so hopefully I'll see better results. As for ambient temperature, it's been a really hot week, but today, it's all cloudy, so I'll do some temperature testing today and post my results.

As for thermal paste, I used the one it came with: Thermalright Chill Factor. Not Chill Factor II, by the way. Just the normal ghetto one =[

I guess I could try remounting the HSF. I also have Tuniq TX-2 thermal paste. Should I use some of that instead of the Chill Factor stuff?

As far as case cooling goes:

I've got 2 in fans near the hard drive cage, 2 out fans at the back, as you can see, another exhaust fan at the top of the case, and 1 more in fan on that swing-door thingy (I broke the other one off because the TRUE was too fat lol).

They're all 80mm fans, if I remember correctly.

Maybe try taking off heatsink, clean the thermal paste, reapply.. and mount again..

Sorry for the stupid one, but just out of curiosity the fan is blowing towards the heatsink right, pushing air towards the fins, not towards the front of the case?.

Didn't even click that I've been posting in your watercooling thread.

Anyways, that case is horrible for cooling modern hardware. 80mm fans are garbage unless you can deal with some noise to get decent CFM from them. Also seems like your case lacks any front intake, unless its hidden behind the ultra restrictive hard drive cages. If that's the case, I'd drop the hard drives down to the bottom and leave the top totally open (if possible), so that some fresh air can get into the CPU area. And if you are able to do that, keep all those cables out of the airflow.

Depending if you could deal with 30dBA+ (your current fans might already be near that), any of these should give you a bit more airflow:
NCIX.com - Buy Scythe Kama Flex 80MM Cooling Fan 2500RPM 30DBA 34CFM FDB - SA0825FDB12M In Canada.
NCIX.com - Buy Scythe S-FLEX SFF80D 80MM Cooling Fan 2800RPM 32.4DBA 40.2CFM FDB Made by Sony - SFF80D In Canada.
NCIX.com - Buy Zalman ZM-F1 Plus 80MM Silent Case Fan 1700/2800RPM 20/32DBA 3-PIN W/ Noiseless Connector - ZM-F1 PLUS In Canada.

However, you could just buy an Antec 300 or Cooler Master CM690 and get a far better laid out case for airflow without spending much money.
