Bummer, do you have any spares?

Man, that sucks. But the air testing isn't much better than just running a pump/rad loop for a bit to check for leaks. Either way it's impossible to tell when a part will leak in the future.
That's one reason to have rads as intake on front instead of on top.
Not that I'm following that advice. If mine leak it's almost all over the motherboard. Mine is on qdc at the rads and block ends. I run just pump and rads, then pump and block separately to check for issues.

My only issue with using it as a front intake is my storage drives are in the way in this case - I really want the new Phanteks Enthoo 719 as that is a case that FINALLY has the space I want . . . But I've always been a bit of a size pimp . . . *laughs*  Saving for that, as well, but now derailed just a little.

Unfortunately, thanks to the fan shroud I was using to hold the old rad up from the case a bit for better air flow, I would need something with standard fan spacing . . . But I do appreciate you stepping up like that! That's the awesome spirit of this Folding Family that I love!

Wow, ModRigs . . . I'd forgotten I had filled those in for my old builds . . . yeah, they are VERY much out of date. I need to update them to the current systems, for sure!

That's absolutely awesome stuff! Thank you Scarlett, pretty darn nice of you. 

Now that I've gotten the water loop rigged up and running for a few days, and have been folding full power for more than a couple of hours at a time, holy CRAP what a difference!

First off, the big radiator and I got some new fans based on what the old skool mod gawd himself, Bill Owen (www.mnpctech.com) had to say mean that the heat just doesn't build up in the loop like it used to.  At full folding power, and this is with a base 2070, a 1070 FTW and the loaned 1080ti, the hottest temp reading inside the loop is one of the GPUs reporting 54c on the die.  The CPU die is reporting JUST shy of 43c.  If I want to put up with a little more noise, the fans will pull enough air through to reduce the temp by a good 4 degrees. At some point, I need to get a waterproof temp probe and put that in the reservoir to get a direct read of the water temp.
 
PPD wise, with the borrowed card, I'm now getting between 3.3 million and 4.1 million PPD on the single box (Varies on WU types, of course) and when I added my secondary box with 2 1070s, my avg kicked up to between 5 million and 5.5 million PPD, again, depending on the WU.  So, those numbers make me a VERY happy camper.

This means that I'm now well into the 'finding and stashing money away towards a replacement video card and associated accessories' as well as aiming at a new case to house all of this in.  If you'd like to toss a few bucks into the pot, please let me know and I'll provide you my paypal information!

Also, another update for me is I FINALLY got a bite on the employment front! Did initial interview on Thursday, got fast tracked to a 2nd interview that was thought to be today, but the manager in question didn't have time, so I'm waiting to hear back on the date/time. The ease that of the first interview combined with the fact that I had previously interviewed with the same manager in Oct of 2018 put us both at ease, and I have a GREAT feeling moving forward!
 
On that note, it's time to make sure the kids aren't going to damage each other on their day off from school.

Hope you get the job. Soooo, what kind of magic fans did you get?

These are the magic fans - https://www.newegg.com/p/2BJ-0034-00001

Quite nice ones, they seem to last pretty well. 

I myself used these for many years: https://www.amazon.com/dp/B07CG2PGY6
 
Not sure how the two stack up, but from converting CFM to M3/H they both seem to push about the same amount of air.
I would guess the limiting factor is the current provided to the fan.
But if you want higher cooling, you can always double them (fans both on the top, as the bottom of the radiator, one pushing the air into the radiator, the other ones sucking air out of the radiator).
 
Then set the beta flag, so your GPUs will work a little harder (run hotter), and get more points 
 
Also note that regular tap water, and distilled water is corrosive.
It's best to equip your radiator with a specialized coolant liquid.

Tap water may be corrosive but Distilled water is the base of those coolants to begin with. You can't stop corrosion, it's just that liquid flow that eventually wears through the metal.

I use these awesome noctua industrial fans. 2000rpm max full pwm. I thought about the 300tpm variant but decided 2k was enough. Fully waterproof and sealed. Can't hear them much either at lower rpms.

To clarify a point, the additives should be aiming to bring it back to a 7 ph, which is a true neutral, but also adding enough free floating material to act as a buffer so the purified water itself isn't trying to steal ions from the metals in the loop.

But that's just a nitpick over terms, really.

On the other hand, I am happy to report that I have now in my possession a new RTX 2080 XC Ultra that I'm just working to cross the threshold to purchase a waterblock for! Freaking excited to be able to pull the trigger on that, then get it installed into the current loop!
 
Can't wait to see what that does for my numbers, esp paired with the borrowed 1080 TI from the_scarlet_one. I'm occasionally pushing JUST up to the 6 million ppd point every now and then over the last day depending on the exact combination of WUs I'm working on.
