Severe overheating issue with stock processor

[Fallout2man]

I recently got a new computer from newegg, assembled it yesterday. it was a big tech jump for me (my old one was a Socket A if you want a point of refference) and after finally getting it all pieced together it's become totally unusable.

Parts list:

Case: Sunbeam Transformer IC-TR-BA Black Steel ATX Full Tower
PSU: COOLER MASTER RS-600-ASAA ATX Form Factor
Mobo: EVGA 122-CK-NF63-TR LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard
Processor: Intel Core 2 Duo E6550 Conroe 2.33GHz LGA 775 Processor Model
Memory: OCZ Flex XLC 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit
Graphics Card: MSI GeForce NX7300 LE

On boot the temp climbs at a steady 2/3 degrees per second until it shuts off. I can't figure out why though. All the fans are working, and the case has a lot of fans I might add. The only possible culprit I personally can think of is the thermal paste on the Stock Intel CPU heatsink/fan. It got smeared a bit when I was fastening the fan to the motherboard since It was my first time working with a non-screw-based fan. I was told this probably wouldn't do this though. Is the processor just bad? Any help would be extremely appreciated since if I can't get this sucker to work soon I'll lose all computing ability in the next few days.

are you sure you pushed the pins in until they clicked? a lot of people dont secure their heatsink too well. It take a lot of force to get it in.

Yes, remount your HSF. Take your time and do it right. You must be getting terrible contact for this to happen.

I feel your pain "Fallout2man" i'm dealing with this issue as I type this. I bought components to build two systems exactly the same except fo the CPUs. One was the E6600 and the other one was the E6550. The system with the E6600 ran perfectly. The system with the E6550 would not boot up and by touching the fan fins, the temperature was hot to the touch. (if the contact is not good between fan and cpu the temperature won't be so hot). I'm no computer-building slouch so all the minutia about making sure all the connections are properly set and the CPU fan is making good contact with the CPU has already by taken care of. Regardless, I did my step by step troubleshooting. Replaced one component at a time until the only thing it could be was the E6550 CPU. That was yesterday, so today, I went to a different vendor and got me another E6550 and installed it .... same result. I also swapped cpu back and forth on both computers and the result is always the same... E6600 works, E6550 doesn't. My motherboard is a Gigabyte GA-965G-DS3(rev. 1.0).

Hope to find resolution to this soon

err, just checked the spec of the motherboard I bought from newegg.com (the Gigabyte GA-965-965G-DS3(rev 1.0)) and it says that the Front Side Bus is 1066/800 MHz. The E6550 FBS is 1333 MHz (that could definitely explain the over heating). must learn to properly read the specs before buying. The E6600 FSB is 1066 that's why it works fine. What's silly to me is that the lower numbered E6550 is clocking higher. I didn't bother looking at the FSB speed because at least in my math E6550 is less than E6600. In retrospect I think Intel the original batches as E6x00 and the second batch E6x50 O*&%T(*^%$(^*%(^&$(&*%(%(^(&%%&..........!!!!! o well, live and learn

To the guy with the temperature ramp -- yeah remount your heatsink/fan
and be sure to apply a uniform layer of thermal paste and don't smudge it
while you're securing the heatsink.

You'll get bad results if the paste is too thick or too thin or lumpy. Since you
have to reapply I don't even know if you should apply a fresh paste layer or if
you can salvave what you have -- if you used the stock heatsink's stuff it might
have been thermal tape/wax stuff which is a little hard to scrape/clean off
since it'll be kind of crusty plasticy waxy. Careful scrape, isopropyl alcohol,
hair-dryer to dry, repeat as needed.

If you originally had thermal grease on there it'll be pretty liquid and easier to clean
off.. same deal with the alcohol, wiping / scraping off, hair-dryer to gently dry
don't touch the clean surfaces with your bare fingers or at all ideally.

If you've got to / want to ditch the original paste get some thermal grease from
someone or order some higher end stuff if you want like Arctic Silver 5 or
Arctic Silver MX-2.

Then follow its instructions for application and be sure the heatsink is fully
locked in snugly all four posts.

I'm not sure I understand your problem from your description.
I understand you say it's running hot.

But FSB 1333 or FSB 1066 shouldn't matter if you have a motherboard that
supports (in practice) FSB 1333 it'll pretty surely work at FSB 1066 also and the
default settings will be right for whatever processor / memory combination you have
for the most part.

Some of the new FSB1333 motherboards may not support DDR2-533 PC-4200 memory
though.. but they should support any CPU from FSB-800, FSB-1066, FSB-1333...

Several older FSB-1066 rated motherboards will support in practice FSB-1333 CPUs
even though they weren't specified for it. Ask around on the Intel forum of
xtremesystems.org or here about your SPECIFIC motherboard model version and
chipset.

Anyway FSB 1066 = 266 MHz , FSB 1333 = 333 MHz so no big difference as long
as your motherboard itself can handle the overclock it's not uncommon for people
to have ran (overclocked) motherboards beyond that for quite a while.

Anyway my point is don't assume it's incompatible without more digging, and don't
assume you're necessarily going to have strange thermal behavior because of that
either.

Of course processors that run faster generate more heat usually, but it shouldn't
be unreasonably bad at the CPU as long as the motherboard is giving the CPU
reasonable frequency and Vcore. Check the Vcore some motherboards may
overvolt the CPU BY DEFAULT (BAD!) or if they don't recognicze the CPU model
because the motherboard needs a BIOS update or something...
