jiae's two cents you're coming at you with a vlog I'm going to be working on the test rig back there in preparation for a video I'm doing for Friday something with that over there and I'm glad that I figured it out today otherwise Friday's video would have been screwed but if you follow me on social media then you would already know what the topic for today's video is so there's obviously some incentive on why you guys should be following on social media but the pump has died in the test rig only one month after using any fries in it is that the reason why I died I don't know we're going to find out this is the any fries mixture with some emerald green dye that I put in there because I want to be a little darker I don't think the die had anything to do with my pump dying a little bit of a pun there I guess but my lane DDC has died so what I've got to do right now is I'm going to swap it with another laying DDC fortunately I've got a ton of these pumps laying around but I want to show you guys what's actually happening here if you listen closely you'll actually hear this pump start and stop three times I don't know what it's doing but it's just kind of looping through there so obviously there's a short or something is causing this to click off and I don't know what the problem is as we're going to open it up and find out now I'm also not saying that the coolant is what caused the problem but I'm kind of wondering if maybe something here might have caused this o ring there's an o-ring that goes around right here that protects the actual blade or the impeller from the electronics this is the o-ring right here it actually just came out but I don't know if that's what failed I could just be electronics that failed it just could be a random failure I don't know where we're at the whole point of today's video but take a listen but the first thing I have to do is actually drain the loop before I can even get in there so let's go ahead and do that okay I think I'll also take the opportunity to get rid of the tubing that kind of died itself purplish red color here it's still weird to me that dyed itself this color after the green coolant was in it this tubing never had red in it it only had green so weird now the cool thing about this being a DDC pump is I can just assemble this without having to take it off the side of the rig I just flipped the rig on the side and have access to it from the bottom now I'll be honest when I say that I was pretty damn frustrated when I turned on the system today and it stopped me from getting the work done that I had to do for a product video that's coming out on Friday but at least we can look at the bright side we get to take stuff apart we get to figure out what went wrong or try and figure it out anyway and I get to make a video for you guys where you can see that things aren't always perfect things are never perfect actually and when it comes to water cooling yeah it's that much more of a pain in the ass when something goes wrong but I still enjoy it I'll still do it I guess I just like punishment there we go last screw so I can do this one-handed it's so easy and take off yeah feels dry just dry in there full ring appears all right pull the different blades on this one than that one mo it's actually quite different the o-ring looks fine so alright at that point we definitely can't not call this fluid related interesting that there are two different impeller designs though I mean everything else about these pumps are the same to take a look at them here you can see this one's a PWM obviously it's got the four prongs on there that are soldered this one does not have anything right there on the PWM side of it but they are the same I could also just replace them he's just sitting here with a magnet these are magnetized so they basically just hover and spin so I just pulled that one out I could literally swap them if I wanted and then that one could go in there and then we're good I'm not sure if there's any benefit to this one over that one they want to go with this one just to see what happens so here's the o-ring right here everything is perfectly fine with it I'm very confident in saying that this has obviously nothing to do with the coolant the new pumps already in there here's the thing let's go into this let's power this on and let's see what happens when I try and run I think we're just going to see it kind of do little just like little quick jumps of power and nothing's actually happening and if it works out of the case then it would be weird if something just caused it to randomly short let's check it you know well it works just fine outside of the casing well I'll be damned I'm glad that it's not bad that is so weird I don't know how it could have been shorting huh so here's my theory this is a typical cover you'd find on one of the DDC is about any of the custom tops or anything on them you can see there's a part right here where the wires have to pass through now when I look closely at these I can see where it looks like they've been smashed but it doesn't look like any of the wires were exposed but all it takes is just a tiny tiny tiny bit of exposure like if you can't even see with your eye it could still be enough to cause a short now when you push it in the plastic housing right here it doesn't actually kind of smush against it like it does on the Alpha cool housing so I think that that might be it this one's got a little bit more of a gap for the wires to go through and I think over time it just eventually created some sort of a short that way but I'm happy to say that this pump does indeed still work it's actually a really good opportunity to explain to you why you shouldn't run your pumps dry even though you just saw me do it do as I say not as I do now these guys actually have a really nice bearing that's built in right here on the motor so these are actually floating I mean as I showed you they're just magnetic sitting in there floating on like a like a fluid bearing if you will the fluid that goes in your system is what actually causes these things you have a gap between the actual spinning impeller and the housing so that's why you definitely want to run them dry so I guess the question moving forward now is whether or not the new one is going to have any sort of a problem with pinching I mean I could end up using this plastic housing and getting rid of the heatsink one but the heatsink actually gives some cooling aspect to those electronics on the bottom of the pump those can get really really hot so I guess we just have to put it back together now and see what happens so yeah I'm going to put the other impeller type in here I should even do this but I want you guys to hear the sound this is what that different impeller type sounded like in here when it's running dry yeah that's bad it's really bad well I think the pinching thing I was talking about is definitely what was wrong because now the new ones doing it and I even started to smell that little familiar blue smoke smell you know I'm talking about yeah so I might have just smoked this pump literally it appears to be it's this metal housing so I might put the plastic one on the bottom go ahead and remove this try and see if I can salvage this if not we know the other one's good right I mean that's a good thing you guys have ever fried anything electronic then you know that smell so just as I thought this metal piece right here is pinching on here you look closely you can actually see where it is squishing the wires and that's what's causing us to have a short I'll be honest I'm really happy that has nothing to do with the antifreeze that was in the system because I know a lot of you are running antifreeze and I really didn't think anything was going to go wrong in this system I still would say don't run glycol-based coolant with PE TG rigid tubing in fact all of the manufacturers of PE TG tubing say don't use glycol-based coolants with them and there is a lot of glycol in any freeze for automobiles but this system has no PE GG in it anywhere and it would have been really weird if it somehow dissolved a rubber o-ring which was part of my concern but that doesn't appear to be the case at all so my assumptions were correct when I thought that this might have been causing a pinch and it was and unfortunately it killed the replacement pump and the original pump works fine after being pinched which is funny maybe it's because it killed the PWM or something and the other pump I just have no idea right let's take it apart and look real quick there we go right there hope to have I build you a smells magic smoke if you've ever smelled it oh man it's funny this little this little bear component right here you can see it up close that little burned component right there made this entire room just smell so disgusting it even kind of puked all over one of the coil packs right there anyway guys time to get out of here I'm gonna go ahead and finish off this video by putting the system together and playing with my new Rhino motorized slider to give you some beautiful shots of this it's a very pretty test bench I like this test bench the Praxis web bench it looks so damn good it's interesting that when the problem turns out to be making sure that you have a nice snug fit between two parts that make together I'm not talking about guys and girls I'm talking about a pump housing and the reservoir to make sure you don't get a leak well unfortunately in my case and ended up causing me to uh to short out the pump oh well guys enjoy this epic b-roll and I will see you in the next one you you
