What can I do to keep things cool enough in a case with few and small fan mounts?

[CharlesMabe]

I'm building an HTPC that is a mid-power gaming machine and a work machine that will sit under my TV and look beautiful. I bought a IR receiver that has an LED display and two navigation knobs, but it uses two external 5.25" bays (it covers a lower one). To give context, I am using a HEC 7106BB case-- which is one of the only cases with three or more vertical external 5.25" bays-- and the case will sit sideways and have an Antec 30126 VERIS Premier Multimedia Station panel installed in the front. Look at the below images to get an idea of the kind of awesome I am pulling off.

My main point with the above information is that I don't have a lot of case choices that will make the IR receiver panel possible without the case sitting upright like a tower, and I was lucky to find the HEC case choice at all. I don't want to change cases (although I know of one more case option, which I won't bring up here).

So now to the main problem and question. The HEC case has few and small external fan mounts to pull air into and out of the case. Here's the Newegg listing for the HEC 7106BB HTPC case. I got two tiny vents up top and two 60mm vents in the back. I don't get what they were thinking. Anyway, I'm installing a Skylake i7-6700 and a GTX 950 in there, and I had planned on a closed-loop liquid cooler for the GPU. Am I going to get enough air flow to cool off this system? And if not, what can or should I do?

Are you using the smaller bays for anything?
You can get mounted fans that will fit both the large and smaller bays.
or you can DIY it
On one build I popped out my small bays and mounted a mesh screen and a fan behind it.

The Intel chips have very good thermals these days, unless your OCing it then I wouldn't worry to much about the chip.
From what I have read online most versions of the 950 do not run that hot.

I would take your system and run it through some benchmarks or stress tests and record the temps before throwing money on a problem that might not exist.

I'm not overclocking. In fact, I got Skylake and the GTX 950 because of the efficiency. Also, I'm not using the 3.5" bays, so using them for fans sounds like a great solution! I didn't know about that one.

I'm still up for more opinions from anyone else, though.
