I am using an H60 water cooler for my intel i5 4690k, and I have a corsair c70 blue led case, so it has 2 intake fans on the front. My cooler's intake fan is connected to the rear of the case, and was wondering if that's where it's best to have it at or if it should be moved to the side or top. I also have room for more fans, so where could I put those as well for better airflow?

To be honest you could set the fans however you want and you would be fine, that CPU cooler is so overkill for a non-overclocked CPU and the GTX 970 runs so cool.

The way I'd set it up though is to have dual intake fans on the bottom of the case to feed your graphics card with plenty of cool air considering that's the hottest thing in your case (despite being very cool). Then I'd have the CPU cooler as a top exhaust. Then you've got a clear airflow design from bottom to top, the graphics card has plenty of cool air and any hot air in the case will be exhausted out of the top.

Having the fan on your CPU cooler pushing air into the case will give you lower CPU temperatures because you will be getting fresh air from the outside of the case. It will make the inside of your case hotter though so it could increase GPU and motherboard temperatures. Obviously that means that if you have the fan blowing out of the case, you will be taking the hot air out of the case so your CPU temps won't be as low but motherboard and GPU temps might be a bit lower.

The way I would arrange your airflow would depend on what GPU you have, how many case fans you have and whether you've overclocked your CPU. Let me know those things and I'll make some suggestions.

Yes, the fan is on the cooler. I have a EVGA GTX 970. The fans I have are 2 120 mm intake fans on the front of the case, and an intake fan on the rear of the case which is on the H60's radiator, so a total of 3 fans. I have not overclocked my CPU.

For a mild overclock, keep the Vcore voltage to stock, and turn up the speed. The stock cooler is still enough for the job.

For a big overclock, increase the Vcore voltage, and see how far you can push your CPU.
Only problem is, the more you increase the Vcore, the more you shorten the life of the CPU,
and most programs will not noticably benefit from the speed increase

If I were you, I would sell the water cooler on Ebay and use the standard air cooler.

The same setup would probably be fine, we're only talking a few degrees difference in CPU temps. You could potentially lower CPU temps a bit more by having a bottom intake fan, CPU cooler as a rear intake and a top exhaust fan.
