I'd like to see some quad and more notably i7 temps.

The thread is getting quite big indeed.

Here is a link to the temps I posted 1-2 weeks ago:

I will have updated ones soon, after I remove the NB/SB and MOSFET blocks from the CPU loop. It should take off about 5C from the load temps. Adding a 2nd pump already knocked 2C from those temps.

Ya those are great. Let's see some 4+ghz. Then we can talk.

Yeah, temps are really nice! But it does come with a lot of noise It's nice for OCing....
And that block....W.T.F.!!! That is a piece of junk when you look at it I'm not familiar with Waterblocks, but I sure can tell it's poor quality.
Now I am changing the block asap for sure!!

Was trying to OC my 940BE to higher clocks, but I just can't seem to get it stable despite the low temps. Right now I got it stable (again) @ 3808MHz, but I need 1.54V for that, so the idle temps have increased dramatically to 34C.

Have capped the TEC power to 55%, otherwise I have to spin up the fans.
So in my case 3.7 @1.47V is much better if you look at noise/temp combination.

I am still looking for a more quiet solution so I was thinking of buying these new Fans from Feser/Noiseblocker:

Air Flow 1: 150.2 m3/h max / 88.4CFM
They are not as powerful as the 38mm Kaze Ultra's but they can provide alot of pressure with less noise.

I'll be curious to c what your new idea is

I set mine at a minimum of 60%, I find it comfortable enough for idle running. It gives me 28-30C idle with 24C ambient.

I finally found my USB wire so here are some pics of my case:



First setup with single MCP655:




Current setup with dual MCP355:



The white thing between the FZEs is a remote temperature sensor.
I've really got to redo my coils and cable management but I'm waiting for all this modding to end first.
I'm still working on my insulation. I got 2 cheap 38mm fans for push/pull setup and some 38mm shrouds are on the way too.

1cm thick rubber floor tiles turned out to be the best method so I'm making little boxes for each component. I also got some 1/2" ID foam tube that usually go on water heaters for my tubing and fittings. I use compression fittings so more metal is exposed than with barbs.

I'm going to be building my Ghetto Boreas stand this week.
It might actually help lower temps even more if my idea works the right way.
When I'm satisfied with the design, I'll have a stronger one made in a single piece.

On an unrelated note, I've got a 2nd GTX295 coming in to go QuadSLI.

Can't wait to c the result of that "boreas"
And I like the ghetto res-stand, LMAO. Simple, but effective!!

Looking at your rig and mine, cooling isn't the problem, what is, is the damn noise. Need to do sumfn about that too. As soon as those Feser fans are out, I'll be testing them to c if they are able to cool the FZE-rad enough at highspeed; would be noticeable by the load and coolant temps I think.

BTW, how did you measure your flow rate? I'm curious to c what my flow rate is. If it's too low, I'll mod the MCP350 to a CMP355 (done in 5 minuts).

I use a Koolance flow meter:
http://www.koolance.com/water-coolin...product_id=740

It's not recommended to leave it in permanently as it adds restriction itself too. There is no need to monitor the flow 24/7.
It plugs into a MB fan header and reads mL/m as RPM.

If it works right, my stand should lower the noise level and make fans more effective so it could be possible to change them for slower/quieter ones but with the same results.
The pump holder on the heatsink is impeding airflow, it should be removed but I'm not sure about undoing the screws of the TEC blocks.

Holy restriction Batman! Way to mess up the block design. Wow is the only word that comes to mind.

If more flow is giving better temps then I think I'm getting the dual top. Still have to wait for EK blocks though. Not gonna be available for another week or so...

In terms of modding the 350 to 355, I am aware that there is a mod but not sure $15 per pump is worth me hassling to mod anything. I will read that guide in a bit and then make the call Thanks for the link though.

@Xeno - those fans are like $35 a pop. A bit too pricey if you ask me...

Edit: Read the guide, damn easy mod. However, voids the warranty...hmm, decisions, decisions I can always reverse the mod but not sure if I can make it nice and clean to the point where it looks like no mod was ever done. Alternatively, a piece of wire with soldered on one end and glued on the other or glued on both ends would work just fine. Even held in place by electrical tape.

What hassle?
Loosen 4 screws at the bottom and pop it out and turn it around. Take the soldering iron and some tin and connect both points...done! You earned yourself another $15...and that's with 1 pump

And yeah, high flow is definitely better than the low which the FZE uses.
My temps dropped significantly!

EDIT:
Yeah I know the fans are not cheap, but if they take away the terrible noise the 2 3000rpm fans make, than I'm willing to pay that much money

Ye, I read the guide lol

Edit: So funny thing...if I get the pumps and the dual top from a local reseller here the MCP350 and MCP355 cost the same (in fact, the MCP350 is priced $3 higher). However, if I order my stuff from Sidewinder of Performance-PCS I can get the MCP350's much cheaper than the MCP355's. I wonder how much I'll get hit on customs...
