Hot summer days, hot computer problems.

Go with a True or Noctua. And If you can sell your case locally put your system in HAF. Best air cooling case hands down.

For the HSF, I will recommend the Zalman CNPS9900, it does wonders for me so far.

For your Case, stock cooling could use an upgrade perhaps. Some Nice Yates or Zalman Fans to Increase Case Overall Airflow, because after all you HSF and VC and NB are only as good as the Air You provide for them.

If you have 3 Free Front Bays, a Scythe Kama Bay is a great upgrade to make to allow yet another un-impeded Path for Internal Airflow.

My thoughts at least,

No way I'm selling my case for a HAF. First off I don't like the HAF's and second I love my Lian Li V1010B and since I only bought it 4 or 5 months ago I don't think I'd even consider anything else.

That being said I removed the second video card to test and I see a huge drop in all temps. Motherboard at 46, CPU idle at 52, and video card at 53. This is without the 120mm fan I added.

So I've decided I need to get a new HSF for my CPU and find a way to cool the dual video cards.

TRUE in push-pull in house with no A/C as well. Works wonders!

pull the PC near the AC vent

Or the House fan like lionred said

get a xigmatek 1283 or a dark knight so you don't have to but the back plate and set it up in a push pull fan setup some links

I reseated the CPU heatsink and fan, replaced my power supply with Corsair HX1000W and added a 120mm fan over the video cards, much better results now. CPU idles in low 50's and is typically in the 60's when working, have seen it in the high 80's/low 90's after running prime95 for a long time. Motherboard is in the low 40's idle and mid 50's under a load. The biggest improvement is the video cards, two Asus EAH4870 1GB DK's running in crossfire idle in the low 50's and operate in the upper 70's under a good load. Below is a screen shot right after finishing a 10 loop run of the Crysis benchmark tool at 1920x1200, very high details, dx10, 64-bit. Results were 34.5 FPS average. You can see the current/low/high temps.

I plan on replacing my CPU fan very soon with a Noctua Push/Pull setup.

Well I got my new Noctua NH-U12P today and set it up with Push/Pull and what a difference. My old stock intel fan would sit idle in the low to mid 60's and would usually be in the mid 90's at 100% but sometimes hit 100 degrees. With the Noctua my CPU idles in the high 30's to low 40's. With 100% load it gets into the mid 60's, so now at 100% load my system is about the same temps as the stock cooler sitting idle. Also my video card temps dropped 5-7 degrees too on idle and about 6-8 degrees on 100% load.

This is easily one of the best purchases I've made for my PC.
