The fans of my case are Antec tricool 120 mm ones with a max cfm of 79.They are regulable,so the cfm varies from 39 to 79 cfm depending in if you put it in low,medium or maximum.

So in the cpu I should put or the same like the case fans or any with higher throughput ( equal or more than 79 cfm,that is the max cfm).

If I use only one fan for the CPU, I can put it in the left,pulling the air through the heatsink?(without any fan in the right) . The fan would be a scythe ultra kaze 3000 of 133 cfm and 3000 rpms.

Edit: I just discovered that you said that the pull fan should have more throughput than the push one. So I can use the kaze as pull,that has 133 cfm , and the scythe that I had in the heatsink of 60cfm as push.

A bit less than 79,but is provisional.

Also as the midle fan is, in the left, but behind the heatsink ,there shouldn't be any turbulence or like because having a 133 cfm fan, a 60 cfm fan , and then another kaze. But isn't the case as the kaze that push air to the card is behind the heatsink.

This would be until I could buy a new fan. As now,this month I can't. And I have two ultra kaze 3000 without use.

And I think I don't have a fan with 79 cfm or more , but the kaze.

With the kaze in the left, between the kaze and the seccond rear fan there is only 1,5 or 2 cm (that is only one less compared to the 25mm fan),but shouldn't be a big problem as the air is almost outside the case , and I think any turbulence wouldn't be very bad, no?

As I usually listen music , and with headphones,loudness is not problem,at least until buy other fans with high cfm but slower rpms.

The another kaze in the middle ,in front of the nvidia, as has 133 cfm will not have any problem with the airflow , no?

Ya that looks ok directional wise, but what about the cfm of each fan? Are you trying for a positive, negative, or neutral pressure? The OP is confusing to me, sorry if you mentioned it.

Noise is a big deal for some people, is it for you? Pressure, airflow, and noise are a tricky balancing act and it take practice.

what is your opinion of this (refering to the position of the fans in the heatsink) :

If the fan at the left of the heatsink have more cfm than the one in the right , we could say that in the heatsink will happen a negative pressure , that perhaps is better for cooling the cpu than a positive pressure.

I am talking only of the heatsink.

I suppose you can have a positive pressure in the case if the intake fans of the case have all in total a higher cfm than the exhaust ones,and still have between the two fans of the mugen, a difference of cfm in the adecuate fan to have a negative pressure.

I know that the ideal is have same fans for cpu,but perhaps a negative pressure in this case is useful.

I think i preffer slightly positive pressure, but not sure. But as my fans are regulable , i could create a negative if i want.

Wow!
Nine fans to cool that rig?
That's a lot of fans for that.
I would think six should do it quite nicely.

I get lower temps with the top fan as intake.

Attachment 194794

There are 3x UK 3000s (2 as front intake, 1 as the exhaust) and 4x Silverstone AP121s on the side (intake)
