What a difference a case makes... WOW!

Just moved my system to a new case today, was definately interested to see if any difference in temps and just absolutely BLOWN AWAY!!!

My old case was an AMS G-tower, I bought it back in 2002 when aluminum cases were starting to gain popularity. It always seemed like a pretty decent case, layout was typical, it looked fairly nice, never really disappointed... until now.

I recently upgraded and selling my old parts as a system to a friend, needed a case and decided to cascade mine to his new build and get myself some new hotness. After some browsing and making sure my Tuniq Tower 120 would fit, I settled on the LIAN LI PC-V1000BPlus II Black Aluminum ATX Mid Tower Computer Case from Newegg. Pic:

While, of course, the new case looks very nice and has some more room,etc... what really blows me away is the CPU temps. Since building my E6300 rig, I have been a little cautious going too far as the temps were a little high for my liking. With a ThermalTake Silent Tower in my old case, CPU at 2.8 GHz was idle around 56*C and load was a whopping 80*C!! Was a lot higher than I expected. I know power generates heat but expected the C2D to be a little cooler...

So I bought myself a Tuniq Tower 120 CPU cooler, thinking it has to be better than my Silent Tower. Also applied some Arctic Silver 5, and checked the IHS for level surface and didn't bother lapping it because it looked good. At 2.8 GHz, same speed as above, my load temps dropped to 71*C and idle was exactly the same as before, at 56*C. Ok, so its improved so I decide to push the CPU a little more. Still kinda warm for my liking but Prime95 (Orthos) runs rock solid... but I hesitate to go much further. I clocked it to 2.98 GHz and been there ever since. (Load went up 1 degree to 72*C at that 2.98)

Come the new case today, and here are my temps: (E6300 still at 2.98 GHz)

Idle: 42*C
Load: 53*C

I'm freakin ecstatic!!

Load temps in summary:
gTower and Silent Tower: 80*C @ 2.8
gTower and Tuniq Tower 120: 72*C @ 2.98
V1000BplusII and Tuniq: 53*C @ 2.98

In other words, my load temps dropped 19*C just by getting a better case!!! Same CPU, same speed, same components, just new case. While the V1000B wasn't cheap by any means, just thought I would share this experience as some ppl seem to focus on HSF, thermal grease, IHS lapping, and other stuff before recommending a new case. It really opened my eyes.
 
and my idle core temps on the E6400 overclocked at 3600 MHz and above are 28-30C. At full load (orthos running from 5 hours up to 15 hours) core temps vary from 44C to 50C . :D
 
I don't know if it was your case really, could have been wiring or something else blocking airflow. I have an Antec SLK2650BQE which looks very similar to your old case, at 3.22GHz my E6300 was mid/high 50s load w/Arctic Cooling Freezer 7 Pro.
 
Whatever it is, you don't need a $200 PC case to get very low core temps It has more to do with airflow in the case as you pointed out, controlling your fan speeds correctly, and cleaning up any and all messy wiring and other obstructions to good airflow.
 
I'm pretty sure it was an airflow issue. I also usually have a pretty hot GPU, 15k rpm scsi drive, and had enough PATA and SCSI cables that it could get cramped in some places.

My old case had one 120mm fan and a smaller one in front (80mm?). This new one has three 120mm fans and lots more room for airflow. Overall just a much more engineered design for heat management when compared to the "basic" PC case layout.
 
Those AMS cases have very small intakes. An easy way to test your case's effect on cooling is to measure temps when running with an open case.
