Continuing my rig update I though for once to also install the system speaker (lol I know) just because why not?... so after putting some heatshrink tube, here's the old chap :)
Also I thought of a way to mount the Swiftech Reservoir by drilling a hole on the upper chassis skeleton. Ofc I made the hole both on the top and bottom part in order to help me screw it easily.
Ok, it's tiime for Prime:)
I cut a bit of the internals of a small tube that I cut in order to fit a funnel we have for kitchen use (lol).
And here's the preparation and filling the loop.
Good thing is that only one fitting needed a bit more screwing alas I didn't have leaking issues! Felt rather awesome to have such success upon my first watercooling experience xD
OK one thing that it felt rather weird is the loud noise from the Apogee Drive II pump (since it operates at full speed).
I'm attaching for reference the following:
A small video of the pump operating from zero to max rpm
A small video of the pump operating from zero to max and then low rpm settings (via PWM) due to Asus settings on BIOS
More info on that later on...
OK after finishing the loop, I just had to try it as fast as I could lol, so, I just putted the PSU inside, tie wrapping the cables not to create a mess and here we are...
Wow temperature after running Prime95 for about 10mins was 35 degrees!!! And that with both Noctuas performing under 700rpm and Apogee Drive II under 1374rpm at silent use!
Time for some Furmark stress test on FullHD.
Ok 55 degrees ain't bad for 15minute stress test I thought, so I guess test was a success.
Since I completed the loop and since I wasn't aware if it's normal to have such noise in full RPM from the pump, I thought about contacting Swiftech's support just for advice.
Ofc I provided all the neccesarry info like pictures, videos etc in order for them to be able to hear the pump and they kindly responded in every email.
I quote a part from one of their emails (from Bryan) as it troubled me a bit:

Hi again Marios,
OK, there is an issue with your loop design and it’s likely why you’re now having issues with this pump. These pumps, like most water cooling pumps, need to be fed directly by the reservoir so that they won’t encounter issues later on with sucking on air once evaporation starts to set in. I do think that the way you installed this pump is the reason you’re having issues with it. That really isn’t advisable to have a pump like this that isn’t being directly fed by the reservoir.
Ok, so after a lot of thinking (despite being bored to redo anything from scratch) I decided to proceed with the suggested way....
Oh well... I had to remove apart from the coolant, the bracket, the radiator, I had to reposition the fans, put new rubber feet, blah blah blah... assemble everything back... and start the new way that the tubes were meant to be used.
Ofc I tried my best to utilize all my fitings without having to buy different angles, etc.
After some time and re-tubbing everything, I was rather happy with the result, and I think it looks also better than the previous one smile.gif
So now the loop goes like this:
Reservoir OUT --> Pump+CPU Waterblock IN --> Radiator IN --> Ratiator OUT --> GPU Waterblock IN --> GPU Waterblock OUT --> Reservoir IN
Not bad at all.
Sadly despite working just fine, I haven't saw any major difference in pump noise so after emailing Swiftech (Bryan) back he responded the following:
Quote:
My suggestion would be to add a drop or two of dish soap to the coolant. It will act as a surfactant and a lubricant to help quiet the pump and push the remaining air to the surface. You should then run your pump at full speed for a couple of hours to circulate it. Let me know if this resolves your issue or not.
I putted 2 drops of dish soap (after reading some other articles as well) and it definitely helped a little but I'm working on it in case it even gets better in future. Good thing is that sound is just audible above 2200rpm and even then it's not annoying. It gets annoying above 3000 rpm where it doesn't actually need to go or helps more imho.
Also, temps got better with the new loop for some reason. Maybe Bryan was right in the first place!
It's fantastic and I didn't expect such difference tbh.
Last but not least some FireStrike demo benchmark
Certainly not anything super impressive (as I'm running without OC on both CPU and GPU) but not bad at all.
The moment that test was off I checked the temps monitor and largest temp I saw was 51C degrees on GPU and 47C degrees on CPU under FireStrike Demo.
Anywayz, stay tuned :)

wow i cannot believe you finished something as complicated as this and that too, with a success. i am sure i will not be able to get done with this at all. keep posting moe
