View Full Version : Bottom rad in CM690 II Adv.

So I'm planning to install a Koolance 2x120mm rad in the bottom of my CM690II Adv. case and I don't believe one will fit with my current psu. The psu I have is 8.5 inches (includes modular connectors) and from my measurements it seems like I need a 7 inch max psu.
This is beginning to sound more like a PSU section topic than liquid cooling but I figure you guys would know best.
I have my measurements but just in-case I wanted to ask you all if any of you use this rad in this case and what to look for as far as psu lengths.
I'm kind of wanting to pop in this psu:

Though, it's modular as well so it may be longer than the 7.3 inches it says which is already .3 inches over what I think will fit.
And yes, I know.. 1200w seems a bit overkill but that's what we do here right?

Also, since I'm already making a topic I have another question: Will 1450GTs be enough for this rad? I already have one of these rads in the top of my case with two 1450s in push (outside air inwards) and I can feel a lot of air moving on the suction side of the fan but under the rad I hardly feel a breeze. I can't fit another set under the rad due to the cpu block's mount sticking out. (For the bottom rad I plan push/pull so it should be fine. Worried about my existing top rad config in this part of the post)

One more little thing: I've been noticing some metallic type particles in my res. Could this be from the silver coil? I washed out all of my components before-hand very well.

Sorry for the long post. I hope you'll find the time to help this newbie. :D

This is what I had to do to fit a 2x120mm radiator and my Enermax Revolution 85+ From the looks of the AX1200 it looks like the same length as the Enermax.
What I ended up doing was using the Lian-Li PSU extender bracket. It required some dremel work to cut room for the PSU to pass through and then tapping holes to screw in the extender bracket into the case.

As for your fan questions, I'm not sure how the fin setup is on the Koolance but for my EK Coolstream 240 I used Enermax Magmas which run at 1500 RPM and I never had an cooling issues.

The metallic things in your loop may be some flux that didn't wash out.

I had the same idea but I forgot who made those. I'm alright with dremeling (though I'd like not to) but the whole hole drilling and tapping thing I'm not really used to. I may have to end up doing this as my last resort.

I'm using the 20fpi version of the Koolance rad. I'm not really have cooling issues but I feel my temps could be better since I'm not getting much air flow through the rad it seems.

Can this stuff get stuck in the cpu block or harm the pump?
Thanks for the help, ohms!

I guess it all depends on the size, I'm sure if it gets into your block it can impede flow. I never had this problem so many someone else could chime in on the subject.

This is PSU Extender Bracket -> Here (http://www.frozencpu.com/products/7798/cpa-252/Lian_Li_Power_Supply_Extension_Bracket_-_Black_PE-01.html)
As for tapping the screw holes, it's easy. Just drill holes smaller then the bore size of the typical M3 screws then use a tapping tool to create the threads :)

Ah, yes. I never said the size. The particles are very very small.

Awesome. Thanks a lot! I may end up going that route.
My swiftnets fits fine....

DTR, he also wants to use a PSU much larger then yours.

Though, it was of some help. Your psu is long for the wattage compared to the others. Apparently your psu is only .29 inches shorter than the 1200w. That is unless I'm missing something.
Also your rad seems to be .8 inches shorter which helps in your case.
So that's a .51 inch advantage your setup has over what I'm wanting I think. Which all in all probably means I'll have to do the mod. :(
PS. I'm terrible at math. :rofl:

I can tell you that its tight - real tight to get the molex connecters into the PSU...have to unscrew the power supply (from the back of the case) and 'giggle' it abit to get them in.

i used to install the biggest double radiator there - thermochill pa120.2,
with 16 cm length psu (seasonic m12-700 modular) it fits ok, the shorter radiator you have - the more lentgh psu you may afford
also i have another case with same restriction - 16 cm psu only - where i use corasir tx950 now. compairing to seasonic it is more handy even it's not modular, just because wires bend easy near psu and more soft in common.
for me it is better to get short powerfull psu than restrict yourself with cooling capabilities or use psu extenders.
