can you have too many fans?

just out of curiosity really

i have an Aerocool 500 midi tower Link below

https://www.overclockers.co.uk/aerocool-aero-500-midi-tower-case-black-window-ca-153-ae.html

over the years i have collected fans here and there and whatever i get free i end up just placing them in case.

the case has 2 on the top for a 240mm rad, 1 on the rear, and 2 on the front (pretty standard setup)

i have all the standard ones filled and then i have 3 addtional

1 is where the CD slots are blowing across the CPU
1 is angled from bottom right (behind the original mounted one) facing towards the GPU
1 is just sat on top of the tray facing across.

Yes you can. I'd bin off the ones in orange, you really don't need them and I doubt temps are THAT much better with them if at all.

Have you measured temps before and after you fitted them?
 
Yes, remove the lower two orange fans. They're not helping you in any way but just make noise. You should check if removing or reversing the rear green fan helps.
 
While I agree removing the orange fans is a good idea, that will leave you with a negative pressure case. Not ideal for dust. If you keep the top orange, you'd want to have intake as higher RPM so you can maintain positive pressure.

Agree with this - the bottom 2 orange fans from experience will just generate extra noise - the only reason to have something like the bottom angled orange one at all is if you have a multi GPU setup in a case with restricted airflow and then it would need to be positioned better for the GPUs.

Unless you have a case that is well sealed then ideally you'd want to be maintaining positive airflow so keep the top orange one and increase the bottom fan RPM a bit.
 
leekeene 3x front intakes should give you good airflow. Rear exhaust will help move the heated exhaust from GPU back and out of case. This might be of interest. https://forums.overclockers.co.uk/showpost.php?p=30354296&postcount=4

How can removing fans from only flowing air already inside of case change the pressure? :confused:
Maybe you had a little too much New Year cheer. :p

Because there are three orange fans, not two. The topmost orange fan is blowing in.

Ah, okay. Effectively there is no 3 fans involved in your answer .. and Legend did not specify the one orange intake either, he said fans. :p

There are no orange fans changing case pressure, only a single orange fan.

Besides, thread discussion is mostly about the other two orange fans .. which have absolutely no effect of case pressure. ;)

I'd remove the 2 lower orange fans & maybe the rear exhaust too.. Or turn it around and have it as an intake

This is what I'd do also as the lower orange fans aren't doing much and the rear fan as an intake would help maintain positive pressure as well as provide extra cool to flow over the rad.

Despite the potential theory I've generally found having the rear fan as an intake actually produces worst performance - I've rarely found a case where it hasn't worked better as an exhaust.
 
hmmm, I have 11 fans (12 if you count the psu)

3 intake, 4 extract, 1 cpu, 3 gpu

fans spin slow and quiet

I have 8 fans,2 intake 4 exhaust cpu and gpu fan:)

4x exhaust and 2x intake (assume filtered) means a lot of the air is leaking into case and bringing in dust

Should have gone water cooled maybe less fans then!

Sorry, but to many of us your suggestion is illogical, and we are not Vulcans either. :D
'Water cooled' at 'reasonable cost' is only possible using poor quality noisy CLCs costing 1.5-3 times as much as decent, quiet air coolers .. if you mean custom loop the cost is double, triple, quadruple the cost of CLCs .. and doubled, tripled quadrupled again when compared to air.
 
I have 20 fans plus 1 (PSU) in my computer
2x60mm
2x80mm
2x140mm
14x120mm

So the answer for your question is: NO! :D

but if I put together all computer fans I have it would probably be around 50 :)
