First Custom Loop - Performance Questions and Tips Needed

post #1 of 9
Thread Starter 
Hey all, greetings!

I've just completed building my first custom loop! while i'm very excited and proud, I don't believe i'm getting the performance I should be.

The build:

Fractal Design Define R4
i5 3570k
MSI Mpower Z77
16gb Geil Veloce 2133mhz ram
750 PSU

Loop:

Danger Den M6 Brass CPU Block
Swifttech MCP655-B
Primochill 1/2 ID Tubing
Danger Den DD-Single 5 1/4" Bay Reservoir
120mm Radiator with 120mm Scythe SY12258L

When I start the system up, the temps hover between 40 and 45c.

When I play league of legends, it hovers around 50 - 55c.

This is no overclock at all on the CPU. I had it at 4.2ghz it hovered around 50-55 at idle.

I have the loop going from res to pump then to rad to CPU then back to res.

I believe from the research i've done that it could be two things.

My 120mm Radiator is simply not big enough to cool the right amount. Getting a 240mm rad could solve all my problems (Money permitting, I will be getting on within next two weeks.)

OR

I have my fan set to blowing from inside the case, through the rad, and out the case. Should I reverse this?

Also, I keep hearing some random sizzingling type sounds from either the rad or pump, is this normal for first little bit?

Also, I used distilled water and a silver coil for coolant.

A 120mm rad is just not up to par. I have a bigger rad than that and its not even a custom loop.

The sizzling sound could be air in the loop. That'll affect your temps too.

How is the pump secured? Bolting them down can cause vibration and create noise, just something to consider.

I have it bolted above the harddrive caddy to the plastic. But also have a velco padding between the pump and caddy. I don't think that is the sound I am hearing.

I plan on getting a 240mm Radiator, the 120 is just something I got in a trade.

Is this the normal first air bubbles that will take some time to get out? Or would it be considered something more critical

It's definitely air bubbles, and yes it's quite normal that it takes a day or two for residual tiny bubbles to work their way out of the loop and into the res. It probably wouldn't hurt to rock the case around, tilting etc, to bleed out some of the bubbles a few more times.

Thanks for the reply! I have been doing this and will continue to do it throughout the next few days.

I've had a store bought water cooler before and this is def. way more exciting than it lol. I'm already planning on building another!
