Is it a good idea to leave the PC case open?

[haljordan18]

Hey guys, Is it recommendable to leave the PC case open for a better air flow?
Im asking this because I can see the top temperature gets reduced by 2 o 3 degrees when i leave the PC case without one of the panels.
Your comments are very welcome

Dust.

On the plus side lower temps (sometimes) but on the downside more dust accumulation. The "sometimes" comes in depending on how the airflow is routed, and whether or not the case guides it around the passively cooled components like hard drives and ssd's. Up to you which you prefer, unless it's so hot that you should be adding case fans instead.

Yep, dust would be the big issue. Plus, with a wide open case your case fan's airflow are much less concentrated through the "tunnel" of your case, making them nearly useless.

it all about how much cleaning do you want to do and how much noise can you take. yes open up your case you will have better air flow and you will get better temp. but dust in the long run will make your temp go up so unless you want to clean it monthly with air duster i would keep the case close. note tho even with the case close you should clean it with an air duster once a year anyways. the best way to keep your pc cool is to have 50/50 push pull setup on case fan and upgrade the cpu heat sink. a cheap 212 evo will keep your cpu cool, and it only like 20 buk sometime.

If you leave your case open, then the intake and outtake fans are useless. Only the CPU fan is doing something.
Better clean the inside or your case, all the cables neatly arranged, and you will be fine.
