Ah crap, what to do...

post #1 of 38
Thread Starter 
Update: I stayed underwater and replaced the leaking junky TFC parts with BP stuff.

-------------------------------------------------------------

So I built my latest machine about 6 months ago (i7 980x, 2x gtx480s) and I put in my first water cooled system. I leak checked it for a full two days (seriously).

However in the last week I have discovered not one but TWO leaks on some 45 degree connectors. First one I found was replace but upon refill another one was leaking (in a different place too!). These are TFC compressions and I had hoped their reputation carried over from their radiators. Seems not.

Worst still, I have potentially discovered a third leak after I've ordered a lot of new parts (about $350 total - ordered Bitspower this time) for this loop. I noticed there is an area on the graphics card which is totally clear of dust. So I had a closer look and there is an oily residue on there. This is why I'm thinking it is a third leak.

I am strongly leaning toward scrapping this entire wc loop and going back to air. Two leaks I might have let go but three in a week? All after 6 months?

I don't know what to do. I really don't want dead hardware when I've avoided it this far.

This is why I'm going to stick with air, 0% chance of destroyed hardware due to leaks. Honestly, if you already ordered more WC parts, then rebuild your loop; leak test it. And pray it doesn't leak again.

It's the whole risk/reward situation. I wouldn't WC if I didn't have the money to replace the damageable parts.

Just ask yourself, is the extra performance really that important to me?

The advantage is I can send the new parts back for a full refund (minus shipping) within 7 days. So that isn't the issue here really.

Having the money to replace the parts is less of the issue, I just hate wasting money. The only reason I went with water is because I like a quiet pc and the gtx480s are noisy beats on stock fans. Now there is after market stuff which wasnt available before.

-------------------

The big problem is if I go back to air, I need to get all this wc stuff out of the machine without doing more damage. I know I cannot drain the top radiator fully (even though it should). I also know the gpus have water still in their blocks which will come out slowly.

How was the fitting leaking?? Where the hose attaches, the thread into the "block", at a turning point on a adjustable fitting?? I only had one small leak, it was because I didnt thread the fitting all the way down. It was at the bottom of my res and dripped onto the bottom of the case.

I know the risks, and I am comfortable with them. If you are not, then you can go back to air. Personally I like it wet...

Where the leaks are, all of them were leaking from the anti twist seal inside the fitting. I've had no issues with leaks from the screw thread into the blocks or from the hose to compression.

Here is where the leaks were from:


If the third one is a leak, it will be the same as the left one.

So far both of the (confirmed) leaks were to non vital areas, one was onto the bottom of the mobo section of the case and the other was onto the bottom of the case. If this third one really is a leak then it is onto the graphics card.

Risks are fine when I can limit them through using quality parts ( I thought TFC was ) and done the proper leak testing (which I did). Failure of 3 tfc parts all within a week is just not acceptable. God knows how many of the others in there might go soon.

If there is an o-ring inside of that seal, then it it is very likely that you could have damaged them upon initial assembly.

Let me give you a piece of advice when it comes to o-rings --NEVER, assemble anything with an o-ring dry. Always lube it first. Whether it be using coolant, water --whatever --it is important that they're not dry. That's when you're most liable to do damage to them.

If it is possible, take the fittings apart and slightly coat the o-rings with some WD-40 or another very dilute lubricant.

I have never used TFC fittings, all mine are Bitspower silver compression. 2 of which are 90degree triple rotary, which have yet to leak. If your new Bitspower fittings start leaking, then you may wanna go back to air lol. But I think you are fine...when you get rid of them leaky fittings.

Honestly from the start I wanted to go with BP but I couldn't get enough of their parts except without spending some horrible amounts of money. It seems they're individually sold in the UK rather than in any quantity. However, I'm now paying that price as I ordered BP stuff only.

Either way, I really thought TFC was going to be good quality hardware purely because of their reputation with radiators. I've not heard of issues with any of their stuff until now. A quick google search reveals another guy with the same issue on TFC parts on the same joints. That was back on the 22nd Dec - So I'm not the only one with leaks turning up on TFC joints.

There have been some threads that have popped up about various rotary fittings leaking in those particular areas. From what I've gathered they were either damaged at the factory, or stressed in the wrong angles causing them to separate a little in the rotary part of the fitting.

In either case, I'm running with a bunch of Bitspower ones myself, and I have yet to have a leak after about a month. But only time will tell.
