Is this cooling setup ok?

on fans and pressure.
Fans don't blow at their CFM if there's a pressure difference.
if you have just 1 exhaust fan, for example, your air flowing in by the 6 fans, will be LARGELY restricted, as the force required to add air to the system is much more difficult. I have experienced this a few times, and the effect is surprisely strong.
in general, you want your chassis to be 'slightly' positive pressured. So you want 1 more fan IN than OUT. Negative pressure chassis is a terrible idea, for one, the rads won't get enough air to exhaust, reducing Rads effectiveness, it also cause dust to 'seep in' to the case. Positive pressure does the opposite. But don't get too positive either, cause then you are just wasting electricity by turning on fans by NOT creativing air flow.
I will use top rads as exhausts too.
Just besure you hae 1 more intake than exhaust. (or calculate the CFM (restriction adjusted), and be sure you have aournd 80+CFM more in than out.

so should i have the rear exhaust blowing in?
each one of those fans except the top 3 are about 70cfm each at 2.06 what ever the static pressure measured (cm cubed?) is.
I can not find what the rating on the top 3 are but they feel about the same as all the others.

looks better then before but you still have other fans blowing out like your psu and gpu's now you have more blowing out then sucking in=( not really sure what you could change at this point to fix that tho.i would just watch your temps for awhile and see how it runs.

the psu is borrowed from work in till i get mine in. it would most likely be pulling its own air from the bottom of the case.
i can always take out one of the hard drive cages and use the second intake on the bottom of the case. it can fit 2x 140mm on the bottom.

That isnt a worry... remember when they were mounted at the TOP of cases?

here are my temps.
prime for 30 mins and igpu maxed
ambient is about 21C +/- 5C. i dont know the exact temp in my room
also i am running stock clock
What do you think?
I dont have a pic but idle temps average 24c
also i heard overclocking is better for watercool, but ill do that when i get my new psu in
