They have all been great, quite and super long lasting. I have not had one die yet. Alphacool has some good accessories targeting water cooling PCs with them as well. EHEIM are definitely my favorite water cooling pumps, especially for 24/7 usage. I had a DDC before getting the first 1046 but it broke after 5-6 years (stopped turning on). I wouldn't recommend DDC for 24/7 use, you want a pump that cools itself with the fluid. My first 1046 is almost 10 years old now and still going strong.

The 1262 is a beast, up to 3400 l/h. It is huge and pulls a crazy amounts of power for a PC water cooling pump but it is still amazing.

I always use pure distilled water with a silver coil in it, and a pure copper/brass loop. The silver coils are cheap and do not get used up and distilled water is cheaper, easier, and works better than anything else, also spills are a non-issue. I have never had any problems and I don't do regular maintenance outside of changing parts (which has never been longer than two years).

Agree. EHEIM are a beasts on reliability....more than 10 years working non stop, and before D5 became a thing
I only change now because 1046 was very weak to do the job, and i confess that my D5 Vario on stage 1 is mucchhhhhhh powerfull.
I use car liquid (G12) + destilled water and 1 drop Fairy

No corrosion or strange objects.....

Please don`t put a D5 on same level of reliability as a EHEIM pump.
Anecdotes are fun . I ran a ddc for 11 years 24/7 in an heat saturated only flushed once loop and it even sat stagnant in storage for a year so it was around for 12 years total. The thing is so old I bought it from Petra's with a Petra's top. Retired it after this recent rebuild out of caution rather than performance issues.

hopefully this'll help you with your journey -

ive been running my first loop for I think 1 year now, I put distilled water in it, copper loop and it's still super clean. doesnt really get too hot and runs on pump level 3 of 5 (using a XSPC Photon 240 V2 D5 )



Cleanest way to go and least amount of maintenance lol.

i used the drinking water you can buy at the store , i think a liter was 1$ and used about 3 liters total?


what i'd do, just make sure everything is tight and double / triple check.

I thought everything was tight besides the internal tube in the Photon which caused a super small drip leak and I had to end up taking the whole thing apart just to fix it lol.

run it for a few hours and just let it sit and watch for any impurities going into the reservoir before you put it back in your desk, i had mine on the kitchen table by the sink.

You’ll need more then just distilled water. Need a inhibitor and some biocide in it.

well yeah, i mean, the liquid itself just water. i do not have biocides in my water, only the silver fittings hooked up to my radiator

@ OP -

I do want to show you this too - dont mix different metals in your loop, otherwise this'll cause this issue:

Hi,
I thought even silver and nickel plating could clash.

24/7 usually means 24/7 - 365.. big difference between that and what some are reporting to be 24/7

I had 2 XSPC 5.25 bay reservoirs in a machine that was really on 24/7 no exceptions and they both died in two years, almost to the day

MCP655 lasted a little longer but was still less than 5 years

So YMMV because only you know how long the pump will really be on

Yie....maybe i should say always on, 365 days...

To the user reporting only using water: Soon or later your system, WB, will create galvanization and will be destroyed.
Even use the most pure water, after been purified at atomic level, soon or later it will create impurities and destroy metals....

At least, put a little car liquid. I use G12 from my VAG car mixed with destilled water and no issues.

Serious.....change that.
