Calling all airflow gurus

post #1 of 48
Thread Starter 
Hi guys,
So after getting sig rig I was very pleased. Now temperatures are rising because of summer, and that means my mobo and CPU temps are also rising *gasp*

Currently, I have my HAFX set up like this:
H70 Push-Pull in exhaust (toilet paper test, it falls off)
Top 200mm megaflow x2 - Exhaust
Side 200mm megaflow - intake
Front 230 megaflow - intake
Air duct with no fan in it (lolol)

I wanna lower the temps of my sabertooth and CPU by a couple degrees before the summer heat gets here.

I've read that many people have success by making the top 200mm fans intake. But wouldn't this bring hot air in from the outside? :S

I also have 2 200mm fans left over and 1 140 mm fan.

Question about HAF X air duct: Why is the darn thing so hard to take out? I had to stop for fear of bricking my GPU. Any tips?

tl;dr: How can I improve the HAF X temps in a way that is low-risk and involves just changing orientations of or adding fans. Also, how do I get the air duct out of the HAF X? grrr

Worst case scenario?

Thanks to all

Reverse your two top 200mm, it should drastically improve your temps. More positive pressure in the case is good for cooling the components and keeping the dust out of the case

From what I gathered in this forum, a pair of Scythe Gentle Typhoon AP-15 in a push/pull configuration do wonders ( airflow/static pressure/noise ration ), but again, I'm not a water cooled specialist, far from it, haha

They are the best fans you can get for rads in terms of sound/airflow.

Another question guys: When I turn on the PC my temps are HIGHER than after a few minutes of being on. My graphics card boots up and it gets to 47ºc. After 3 mins it goes to 39 and stays. Same with CPU. Is this normal?

I don't know about you guys but i had better temps with the CPu cooler exhausting out of the top and the top as exhaust...


I had the top as exhaust but it was only 3-4* lower.. iwas getting better temps with the Cooler exhausting out of the top.


Right now i have the hyper 212 exhausting out of the rear and hits 77*c 3.4ghz 1.45v.... i think i did a poor job on seating the heat stink.

yes reverse the top fans, get push/pull gt 15s on that H70 if you have broken 120mms make shrouds. Clean out dust. It's normal for the temps to go down a bit after starting my temps drop around 5 C in 30min after boot-up. Put the extra 140mm in the air duct, if it only accepts 120mm be creative (zip-ties, rubber bands, velcro, etc.)
