Default High case temperature due to bad airflow

Okay, just a question for you guys. The temperature in my case is 42C (IDLE, didn't manage to check it stressed) is this normal for a midsize ATX tower, or does my case lacks airflow.

I will buy a new case soon, probably the HAF932. Will this lower the temps of my CPU significantly?

what are your CPU and GPU temps

if they are within normal / safe range then you don't need to panic just yet

Try experimenting by removing the side panel and pointing a house fan at the components.

Getting a larger case that can use all 120mm fans (38mm deep) can help a great deal.

Well, my CPU gets 68C after 8.5h Prime. And my GPU's get around 78C in crysis (clocked them back to 765/1850/2200 due to the heat/summer)

Volume and balance along with good cable management are the key Provided the ambient temp. isn't the issue.

If the air flow volume of the intake and exhaust are about equal, not taking into account the PS exhaust flow, you'll then have a slight positive exhaust flow volume due to the PS's effect.
For the most part, a slight positive intake air flow volume usually works best.

That Haf932 + Cable management should = you have much better temps.

well....for a start, those cables completely prevent any airflow from the front of the case..... so your CPU HSF is struggling, then add that terrible 250mm side fan, which has such a crap CFM,, there's no real point in having it IMO...

you need a new case so you can loose those cables behind the mobo tray....

That's also what I though, but the 250mm side fan pulls the most air through the case. And this was the best cable management I could do (no room left behind the MOBO tray )

Cables are good, you did well
Your likely issue not air enough exhaust flow though.

A good flowing case will make a big difference.

I went from a cheapo Ultra X-Blaster case to my Antec 902.
CPU Idle temps dropped from 45-ish to 38-ish with case fans all on low in the 902.
