Is my loop supposed to be silent?

post #1 of 11
Thread Starter 
I recently completed a build and decided to venture into water cooling for the first time. I purchased a Swiftech Elite 320 kit. I followed all the instructions, read the stickies and bled the system (which was incredibly easy to do).

What I notice is that the loop makes no noise at all. When I first fired it up there was some sound of water moving through the radiator. My temps seem fine. I'm running a 3770K at 4.6ghz and temps with just a browser open are around 30-40C generally. I'm only cooling the CPU as I there is no block available for my GPUs and I wanted to start basic anyway.

Thanks so much for reading this paranoid post. smile.gif

The reason I chose to water cool was for silent operation; If you can't hear it and your temps are good, you have a successful water cooling loop!

Aside from pump and fan noise, a properly bled loop should be nearly silent.
Certain pumps (ie. 355) can be loud when bolted directly to a case, but if your loop is nearly silent congrats!

Thanks so much. My setup has the Apogee II which has the MCP35X pump. I guess I just didn't expect it to be so easy.

Well done, your loop works!

As mdatmo said, the only noise you should hear is from the pump or fans. The MCP35x can be turned down quite a bit in that loop without losing any performance which will help to keep things quiet.

As for the GPUs, you can get universal blocks which cool the GPU core. They tend to be reasonably priced and can be used on almost any GPU on the market. The downside is that they don't cool the VRMs or vRAM, you would need additional heat sinks and a fan blowing over the cards to keep them cool.

I have the EVGA Classified 680 in SLI which require a specific GPU block made by EVGA. And, as luck would have it I received an email notification about 5 minutes ago that they are available. I ordered two immediately and now it looks like my loop is going to get a little bit more complex.

Thanks to everyone for responding. I turned the fans down and turned the pump up to 100% and it does make a noise but it really isn't noticeable with fans operating. At 35% I can't hear it at all.

I would leave it at 35%

Turning it up will not give you any real gains on temperatures if at all. You can try it if you want - run a stress test at various pump speeds and see what you get.

Good news on the GPU blocks, you are going to love getting rid of the GPU fans. thumb.gif

Silent is good! thumb.gifthumb.gifthumb.gif

However, if you heard water rushing through the rad that means there is an air bubble in there. Maybe it worked itself out but if you hear it again the next time you power up, you should try to move it out of there into the res.

I just ordered my gpu block, i cant wait to get rid of the fan noise. the general guideline is 120mm worth of rad space for each heat generator in the loop since your going to have 3 things in the loop with a 360 rad it should do ok but if you want even better temps without having to turn up the fans i would look into getting some more rad space, just an fyi, good luck

There hasn't been any sound of water going through the radiator since I bled the system.

I already have another Swiftech 240 radiator and I think I have enough tubing left from the 6' that came with the kit. I'll just need the fittings to connect to the GPU block. I need to look that thing up now and peruse the manual.
