Reco's wanted -Koolance Pump dead after 2yrs ... 7970s survived

post #1 of 25
Thread Starter 
I bought this https://www.koolance.com/water-cooling/product_info.php?product_id=296

I did fold 24/7 for about 6 months and have been doing a lot of work/gaming for the other 6 months - so the last year it's been running a lot

2 years and 2 months ago - feels like It died young?

Looking for reco's on new pump or pump reservoir - I'd go with this koolance again if a 2yr life span seems correct...

need to pull trigger quickly as I have to work on this bad boy too .. here what my guts look like atm

EDIT: I also noted that my tubing was sort of flattening out ..... once I added in my second card... is this typical? do you think the flattening of the tube caused trama on the pump?

That said... tubing suggestions are welcome too


Nickel/silver
currently using nickel plated blocks and a silver coil.... could this have killed it? or is the warning about blocks vsr pump?

Koolance's product warranty does not cover the use of 3rd-party coolants, coolant additives, or corrosion. Koolance LIQ-702 or LIQ-705 coolants are strongly recommended to help avoid issues with mixed metals or biological growth. Additionally, do not use aluminum with bare (unplated) copper or bare (unplated) brass in the same system. Do not use nickel with silver in the same system.

Thanks for the above.. was thinking the below would do the trick ... anyone have thoughts or use this pump/rez combo?

Swittech Pump/Rez
primochill tubing

Also on tubing... I last bought 1/2ID 5/8OD .... the primochill tubing is 7/16ID and 5/8OD - i read that the 7/16 will fit on 1/2 barbs ... can anyone confirm

what's a good fluid for EK nickel blocks? I had been running distilled water with coil ... EK but saw this could cause nickel platting issues.... Any thoughts on what coolant I should use?

If you're using nickel plated products (regardless of brand) I would suggest corrosion inhibiting coolant such as EK-Ekoolant. Hell, even local petrol station antifreeze diluted with distilled water is better than nothing.

It's a good top, but for much less money you can get a 35X with res top:

I use 7/16" x 5/8" on my 1/2" barbs. Fits very snug... but some people actually go this size and don't even use any clamps to hold it on (which I still find absurd). I have mine zip tied and I can pretty well yank on these things and they don't move. I'm not worried about a hose just busting off, let me tell you.

Pro-tip: take some distilled water, heat it to near boiling... soak the end of your 7/16" ID tubing in it, then force it onto the barb. That'll give it the little bit of stretch you need to get it on there a bit smoother, plus the water acts as a lube a bit. Then, zip tie/clamp as you like and it won't move. Mine has been running like this for almost a year now biggrin.gif

2 years definitely is not an appropriate amount of time for it to die. Not sure about other pumps, but I know the mcp355 and the others are stated to last up to 50k hours (5 years). So 2 years is not even half of that.

As others have said, I vote for the mcp355, it's a terrific pump with plenty of pressure to get through multiple blocks without a hitch. The 35x is also a great choice.


7/16" will fit on barbs extremely well (just need to heat it up first to get it to stretch). I would also recommend zip-ties for precautionary reasons, although many people do not put anything on and are just fine.

Uh.. the pumps you guys are recommending are all the same as the one he has.. They are all DDC pumps made by the same manufacturer. Just so you know.. Swiftech/Koolance/ect. just put their labels on them..

^^Wirefox, do you get a warranty on that? Swiftech insta voids warranty when their pumps used w/o stock top.
