    I'm not sure if this relates to hardware or cooling, so moderators do what you need to do.

    I just got a intel pentium dual core e2220 @ 2.4ghz and installed it on my rig. It wouldn't load up xp with my bios settings at first, so i had to the set it back to default settings which helped it boot. When i was installing it i saw the cooler was literally half the height of the e2140 stock cooler i got-i thought maybe it's part copper or the newer core 2's run alot cooler. So i went through all the normal steps to install a new cpu and ran 3dmark06 to find a drop of 400 cpu points and about 1500 total 3dmark points. I ran two cpu burns with cpu-z and speedfan. According to a comparison of speedfan and cpu-z around 83C it throttles back to a 6x multiplier-about 1.2ghz. I found this to explain why my 3dmark06 score suffered, but i am nbow wondering why is it overheating. At first i thought that the 83C was my 8800gt but gosh it's both cores! I'm pretty sure the cooler is in good contact with the proc, my case has good airflow (thermal soprano), and i think it's getting enough juice (thermaltake 500w tr2 powering 3 hdd's, 1 8800gt 256mb, 1 dvd drive, 1 x-fi fatal1ty, 3 cathodes, and a wireless card). I'm thinking that either intel shipped the wrong cooler (boost in clock speed w/ the same manufacturing process = more heat right?), maybe my psu can't handle it, my mobo hates it (fully updated asus p5nsli), or i got a bad proc. Any help would be great!

    6x multiplier is also where it idles due to C1E/speedstep.

    83C is too hot, you must have screwed up the heatsink install.

    make sure all FOUR of the push pins are correctly inserted - try and wiggle/tilt the cooler with the system off - see if one corner is 'loose'

    also make sure you have thermal paste on there... the cooler should had some grey lines of paste on the bottom, if you've wiped that off you'll need to buy some new stuff (arctic cooling MX2 being the current favorite)

    Oops, i installed it backwards aka is pushed the pins in then twisted the knowbs (to lock it as i thought).

    dont feel too bad, they dont have much logic to them when installing.

    fairly common is for one of the white pins to bend, so although it 'clicks' and seems to have locked, that pin falls out sooner or later.
