Quieting the pumps shaking the M10

I didn't get a response from Jim at CaseLabs, so I decided to take a shot solving the problem.

As I mentioned before, the 24v pumps seemed noisy. I've been doing some soundproofing around the house, and recognized that the pump vibration might be resonating through the case. Even though I put rubber grommets over the metal dowels or alignment keys, the binding of the screws -> case -> res/pumps was allowing the vibration to fully transmit throughout the case. Separated from the case, it was substantially quieter.

Luckily, I ordered some extra HDD grommets and screws on a whim, even though I only have an SSD. It successfully stopped the vibration throughout the case. It is an order of magnitude better, though I'm sure it could be improved further. I have not drilled new holes in the mount for the reservoir, so it is still set back about 1/8", but I can get to that later. I'm just happy it is quieter!

Oh yes, apparently the fans are a fun cat toy too...

Ambient temp on the CPU was ~34C.

Running OCCT with no overclock is yielding 72C max on two of the cores. It looks like I might need to get these fans back on the radiator. I could have a poorly seated CPU block, but I think the first step I'll take is to go ahead and put the fans back on the radiator to force some air through.

Disappointing! I hope it turns out not to be a radiator issue. I love the return air idea.

Great! Good news and bad news.

Good news is that it seems the simple "set the radiator in the hvac return" works. I proved so by forcing all (not sealed but you get the picture) through the radiator:

With the above picture, there were zero changes in the temp.

Now for the bad news.

This may not be helpful for others. I used hard fittings to connect to my CPU, and it is a huge pain to pull out. Worse yet, it's possible the fittings are pulling the CPU block off the surface of the CPU or otherwise lessening the pressure of the springs on the EK CPU block.

I wonder what was wrong with my temps rolleyes.gif

Seriously folks, please don't drink and install waterblocks.

And now we know:

  1. Stock voltage yields 29C idle and 42C max running OCCT
  2. Forcing more air through the radiator makes 0C difference
  3. Using the 24v pumps at half throttle vs full throttle yields 1C difference
  4. "Please Remove Before Use" sticker yields +30C under load biggrin.gif


Time to overclock!

too funny! wonder how many other people can reduce their temps by 30 degrees after reading this. wink.gif

LOL, hopefully it helps someone! Consider this a scientific experiment to see how much temps are increased wink.gif
