Will My computer be able to cool properly (safely) like this?

Hardware Hub Cooling

I'm getting more and more into video editing recently and i have started rendering something about 5 hours ago, estimated time = 21 hours, 47 minutes. ok that should be fine but i would have to leave my comp on all night which also isn't a problem except for my front led light (Its very bright and blue) -.- i cant get to sleep with the light there so i covered it with a t-shirt (only thing i could find xD) but since the led is in the front where the front fan is, will it restrict airflow and... crash? or will it survive the night? it is not pressed up against the front fan, there is about a 10 cm (about 4 inches for you who use the imperial system for whatever reason) distance between the shirt and the front fan.

----------------My Build (most of it won't matter but its always good to have it in there :)-------------------

MotherBoard: ASrock B75M R2

CPU: Intel Core i3 3240 (im upgrading this, no wonder the 25+ hour rendering time, maybe a xeon)

GPU: AMD radeon HD 7850 2GB GDDR5 (this will also eventually be upgraded, 280x if i can bring myself to spend all my money ;(

RAM: 8GB of DDR3 1600mhz Ram (corsair vengeance)

HDD: Western Digital Blue 1TB order number: 750417

PSU: Corsair VS650

Case: Cooler Master elite 431 plus

No extra fans but stock fans

I have the same case. That front fan is a bitch to get out (and quite loud). I still have it in there (and it makes my computer loud).

Why can't you simply turn your computer around? That would probably work best. Another option would be to put a box or a book in front of the light. Another way is to hang the shirt over the front of the case then on a book or box in front so airflow is not so heavily restricted.
