Is it okay to have no fan/s in the upper area of my PC Case?
I bought a new PC case for 50 Dollars (If i USD), I saw that the PC case had 3 fans infront then 1 fan behind, but I noticed, there is no fan above. Is that okay? The brand is Trendsonic Eclipse EC09a

As long as you have a rear fan exhausting the hot air out of your PC case, and front fans bringing cold air in. You're fine. But if it's in your budget, it wouldn't hurt to get more fans for the top. I got 15 fans in my system, and it cools my computer down perfectly. I mean, you don't have to go that overkill, obviously. But I got a full tower so I can fit that many fans.

It's not necessary, but it's always nice to have.

It'll be fine. Personally I'd check temps using Hwmonitor or something in the default configuration. Then I'd switch one of the 3 front intakes and place it at the top rear location as an exhaust (so 2 intake and 2 exhaust) and see if and how it affects temps.

Just move one from the existing fan places to the top

15 fans?! What case do you have that even allows this many? In general you have room for 3 front, 3 top, 1 rear, and maybe one or two bottom. Perhaps even a couple side panel. But 15 sure seems entirely overkill...
I do recall back in the day a few cases that could fit 4+ 80mm fans in the front, but those were 80mm fans... Not exactly the usual nowadays.

Try to borrow an IR camera and take video of your case while gaming. You'll reconsider "perfectly".

Actually I miscounted, I actually have 14 fans.

3 fans for my radiator (120MM)
3 fans on the lower right side of my computer (120MM)
2 fans on the bottom of my computer (120MM)
1 exhaust fan (140MM)
1 fan on the lower left side of my computer (140mm)
2 fans on the front of my desktop (140MM)
2 GPU fans (blower style) GTX 1070 FE in SLI.

The case I have is the Thermal Take X71 Full tower.

Well then... thats a few fans. Though I suppose I didn't think of counting GPU fans. And I would imagine your PSU has its fan, too, depending which way you have the PSU oriented.


Im curious now though. Have you given much thought to positive or negative pressure in your case? have you got a decent balance, and given thought to turbulence?

Just throw some fans in it and call it a day. People go overboard with fans and over think it and some people just like the look of all the fans.

I have more postive pressure in the case, but I still have an some exhaust fans as well. But mainly just postive pressure.
