Quick question about my rad + fan set up.

post #1 of 5
Thread Starter 
Hi OCN
So I'm planning on going the water cooling route for my i5 3750K at 4.5 GHZ. Currently, I have a dual 120mm radiator at the top, with 2 Corsair SP120 fans. The fans are blowing air through the fins, and out the top of the case. On the bottom of my case, I have another dual 120mm rad with another 2 Corsair SP120 fans. My question: Are the 2 dual 120mm radiators sufficient for this set up? Or are they unnecessary? Another question regarding the bottom rad/fan set up. Should I have the fans pulling air through the fins of the radiator and into the inside area of the case? If not, how should I have them configured?

Thanks in advance.

Sounds good to me, and enough radiator power (If you have a decent one) to add a gpu in the loop. What pump, radiator and blocks are you using/buying?
When it comes to radiators I always want them to get the hot air out of the case and not in. So let them blow outwards. If you want the hot air inside, you must have very good airflow to do it, then it might work.

If its your first time watercooling here's some short advice. Set up loop in this order reservoir > pump > radiator > cpu block > gpu > and back to start again. Can do otherwise, but that is the most used from what I know, and what I have personally done for the last 5-6years.
Remember to bleed the loop (getting the air out), this is done simplest by having filled up enough liquid then leave the cap open on the reservoir. Its important that the reservoir stands higher in the case than the pump, or the pump will be starved. Don't let it run long if it makes a lot of noise in the start, just fill up more and shutting power on and off.

Don't fasten your radiators before you have bled the system. Easiest way to get air of radiators. As you can hold it in your hand and turn it around.

Have fun, you will get addicted hehe smile.gif

The 480mm total rad space is more than enough. I would not bother with more radiator space, but I would definitely consider getting the fans for push-pull on the rads.
The faster the airflow, the more turbulent it is while also increasing the air turnover rate, and with this comes a larger temp differential between the air and rads, increasing efficiency. For me, with a 3930K and 670FTW in my loop with an EX420 and UT60 240, Push-Pull lowered the Delta-T from 6.1C to 4.9Cuunder load. My CPU @ 4.92Ghz doesn'tbbreak 58C and GPU @ 1384core and 7248mem stays between 27-30C.

For the top radiator, I have an alphacool 45mm, and for the bottom radiator I have a XSPC. My CPU block is the XSPC Raystorm. I am cooling a 780, so I got the EK Titan block. The res is the Swiftech Maestrom fitted with the Swiftech MCP35x. And for the configuration, I was thinking since the res feeds directly into the pump it would be: res->pump-> CPU-> top rad-> gpu-> bottom rad-> res/pump. Does it matter which holes I use on the radiators? As in which tube goes in where.

Push and pull is having hair being pushed through one side and pulled out the other side of the rad to increase the total amount of air being passed through, right? I was planning to do that for increased performance and efficiency, but I just don't have enough space in my case. I'm running the C70, and everything's pretty tight as is now.
