Have I ruined my XSPC Rasa 240 kit's pump?

post #1 of 12
Thread Starter 
...or at least gotten myself into a complicated / expensive mess?

Here's what happened: I've been noticing green buildup in my loop, and as my overclock attempts on my Core i5-3570K haven't gone so well, I decided it was time to RMA my motherboard (for reasons unrelated to overclocking) and flush out my system. Today I finally tackle the challenge of putting everything back together and...whoa there's quite the visible colonies living / dead on the pump, and under it. I bought new tubing once hot water couldn't flush out the gunk, and now I wonder if I'm going to have to buy a new pump, or is the whole kit just ruined by organic contamination. Today I've tried running the pump full of hot filtered water for 45min at a time, plus filled 20%-50% by 90% isopropyl alcohol: if it wasn't dead before it probably is now. Even with all that, the colonies / remenents just aren't coming off well at all, and I don't think I can actually take apart this type of preassembled resovoir + pump. And even if I could, I'd probably have to take apart my two waterblocks (CPU+GPU) and thoroughly clean them too, to get rid of the infestation. Though I used a single Killcoil with distilled water and later added some isopropyl alcohol in my loop, seems I probably screwed up royally...and now I still have no desktop, since I can't find my old air coolers.

So is this Rasa 240 kit worth saving? My GPU temps were usually pretty good, around 60C max before I think the VRMs started to overheat (on my 4GB GTX 680), while my CPU was only average...leading me to believe that I never did mount the waterblocks exactly right as my main problem. But as far as gunk leftover in the loop: should I just fire it up and leave it in there until I can afford a proper cleaning of the whole sysyem, or should I give up and get something like the Corsair H100i? (Air cooling was even more trouble than this)

I'm hoping to have this sorted out in the next few days, as my tablet also recently died, so now I only have my (thankfully rather advanced) phone to do my IT work on; it's been almost 3 months now without my desktop.

Put hot water with the alcohol solution and plug the holes and shake it. Loosen up all you can and dump it out a few times. Then be sure to use a silver kill coil and/or dead water biocide. It's what I use and haven't cleaned loop for over a year and it's still crystal clear. Also make sure to use distilled water from the store.

I think the problem is less that you had bacteria in your loop, and more that you used Isopropyl Alcohol to clean out your loop, which your entire reservoir is made of Acrylic.

 

Alcohol will crack acrylic quite easily. And you've introduced a major failure point in your loop by using it to clean it out. Irregardless of whether it was a diluted solution or not.

Never, ever clean acrylic with alcohol. Ever.

Alcohol isn't going to harm it as long it's only brief duration and rinsed, so proof or stop making absurd claims. Getting this guy worried over nothing. It's fine as long as it is rinsed out after use. But if you feel worried about it try hot water and bleach.

 Cleaning 
 
A liquid detergent and water solution is recommended to clean acrylic. DO NOT USE 
ABRASIVE CLEANERS, SUCH AS AJAX, SOFT SCRUB, ETC. ON ACRYLIC. The 
following brand name cleaners have been found to work well with acrylic materials. 
 
  •  Fantastik household cleaner 
  •  Glass Plus cleaner 
  •  Formula 409 household cleaner 
  •  Cinch household cleaner 
 
Scratches and abrasions may be buffed out using commercial polishing materials. Use of alcohol 
greater than 30% and acetone can cause irreversible damage and is not recommended (see 
material compatibility). 
 
....
 
Material Compatibility 
 
Table 1 gives an indication of the chemical resistance of Acrylic. The code used to describe 
chemical resistance is as follows: 
 
R = Resistant 
Acrylic withstands this substance for long periods and at temperatures up to 120°F (49°C). 
 
LR = Limited Resistance 
Acrylic only resists the action of this substance for short periods at room temperatures. The 
resistance for a particular application must be determined. 
 
N = Not Resistant 
Acrylic is not resistant to this substance. It is either swelled, attached, dissolved, or damaged in 
some manner. 
 

 

 

 

 

You need any more proof? Stop suggesting something to OP that will harm his product more than it already probably has. Acrylic reacting to alcohol is a very well known fact.

 

And he didn't run it with alcohol for a short amount of time. He ran it for 45 minutes. EASILY enough to damage his acrylic based components. I wouldn't trust that reservoir even if you gave me $500 to put it in my machine.

Huh. Well there's no leaks in the reservoir at this time. So it sounds like I should just attempt to put it back together (after making sure to dump the last of the isopropyl) and use it in its degraded, infested state for now, as shipping the supplies I'd need would take at least a week.

This sucks dude, if you happen to be in the US I have a spare of that exact pump/res combo, never even been used.

I wouldn't. You run the risk of either a leak developing, or residual alcohol eating away and cracking the reservoir enough to cause a catastrophe in your computer, which puts all of your other components at risk. Something you probably don't want happening after already having gone through what you did.

 

If you ever run into bacteria developing in your loop, clean it was dish soap. Never, ever, use alcohol.

Ah well that's a bummer. I guess that leaves me with just trying harder to find the stock air coolers and mounting brackets, or buying cheap aftermarket ones.

I'll probably end up just trying to sell what's salvageable from the watercooling system itself in pieces, as I'm just not as interested in it as I used to be, or just buy a replacement reservoir+pump: depends on how well the next-generation graphics cards perform, and if I feel the need to upgrade my 4GB GTX 680; I did really liked how well it seemed to perform in temps on water, so I was planning on reseating the waterblock and putting probes near the VRMs and PWMs to see how hot they got...however now I've just lost my confidence in my overall ability to overclock. None of the higher-grade parts I picked out for my Athlon64, Q6600, Core i7 920, or my current 3570K, were ever stable beyond a 10% overclock, and that just wasn't good enough for their premium: I blame a combination of bad luck, impulsiveness, and my own overall ineptitude.

Anyway, I think I'll just do what I can with air again for now, and do appreciate the fast dose of unfortunately visceral honesty.

He doesn't know the difference between the alcohols. Iso is in soap, so no matter what you will be using it in a solution. So here is a little more proper information without someone mixing up what something is with something else.
Quote:
While both forms of alcohol are flammable, the major difference between Ethyl alcohol and Isopropyl alcohol lies in what they are composed of--especially their main ingredient--and their uses. In the case of Ethyl alcohol, this main ingredient is ethane which is found in corn and with Isopropyl it's propane. Ethyl alcohol is used in drinking such as spirits, tonics, liquor, beer, and ales and means it can be ingested. Isopropyl on the other hand is mainly used as a medicinal and sanitary agent such as rubbing alcohol, hand sanitizer, and soaps among other things meaning there is no form that can be ingested.
So this means there is a good chance that isopropyl would be in anything you used to sanitize the res. So the gloom and doom is an exaggration since he didn't know the difference between ethyl alcohol and isopropyl.
