Didn't know where to put this as it's a combination of problems. I seem to have found a very annoying and loud flaw with the Obsidian 250D. Coming from a HAF 932 with a huge fan blowing directly onto the graphics card my 280X windforce was barely audible but now it's in the 250D the 3x fans on the card are having to run at 80% to keep it cool during gaming and the noise is doing my nut in. If I take the side off completely then the fans drop down to 60% ish and the noise drops off a lot but having to take the side off isn't the solution I'm looking for. I've tried leaving the side on minus the dust filter but no difference.

Other than having to go back to a bigger case can anyone see any other solution to this?
 
You are shocked that the tiny itx case has less airflow than the full tower HAF?

What fans do you have in your 250d? I would put a big 200mm at the front, a af120 in the side and two good 80mm in the rear exhaust.

You could also adjust the fan profile with Afterburner if you want them to run a bit slower but this may raise temps a bit.
 
I didn't realise changing the case would affect the graphics card so much. The location of the card in this case is next to a large ventilated panel so the 3 fans on the card can suck air in easily. I've already got a bitfenix spectre pro 200mm fan on the front and an 80mm on the back. The other side has a h100i with both stock fans sucking air in to the case.
 
Would swapping the case to a corsair carbide 540 solve the issue? Going by taking the side off the 250D and it dropping 6C at idle I'm guessing it would. That was the case I was originally going to get.
 
Corsair 540 is a fantastic case and really really good airflow.
I have a watercooled build in it, and it's perfect.

Would recommend upgrading the stock fans to AF120's or something with high airflow are are quiet, as the case doesn't come with a fan controller so unless you manually set them, they run pretty loud.

Or get the NZXT Mesh fan controller as it suits the case superbly. ;)

To answer your OP, in a smaller enclosed case heat can't escape as easy, so dragging fresh air in is good, but the warm air is harder to extract, increasing the temps.
 
Think I may have fixed this with my own custom fan profile for the 280x. Been playing for 30 odd minutes and it's about as loud as it used to be in my HAF and the same temperature as it was reading with the default fan profile.
