As for failing, the fans on the RAD tend to die more often. Then the RAD gets clogged with dust bunnies and needs an air hose treatment or air in a can. Careful not to broadcast that dust everywhere.
If you have flushed clean each part with white vinegar and distilled water, use clear tubing that is durable and flexible, and use a mixture of 90% distilled water with 10% automotive Propylene Glycol coolant, expect many years over a decade of good cooling.
Tubing like Clearflex60 is sold many places in this hobby.
Another plus is a fast acting and high joule clamping surge protector. Mine is a Tripplite. It's survived a lightning strike.
That kit should hold up well.
The only draw back to the D5 is the cavitation that could occur and the binge point in the volute that wear away inside. If the D5 is a variable speed, run it at the lowest possible setting that can keep the computer cool under a heavy load. This will keep the D5 to live longer.
Dont use vinegar for flushing anything,hot water is sufficient. Rad flux is water soluble,not acid soluble. Running a D5 at max will not shorten its lifespan significantly,unlike all DDC bar the 10w,it is widely regarded as the most reliable WC pump available.
Rad solder seams are the main weak point for me,they do develop leaks from the thermal cycling or corrosion.....eventually anyway.

WHen they fail it's not replacing the liquid cooling parts that is the problem, it's the possibility of it leaking on your super expensive mother board, cpu, or video card. Please realize that these horror stories are few and far from, but they do happen can can usually be avoided by using corrosion inhibitors.
If you DO use corrosion inhibitors your pump will be the first to fail after a few years. Then the pump will be the second thing to fail, once it's replaced. The solid parts will last a VERY long time if you use corrosion inhibitors. Keep in mind I'm not including the fans in this explanation, they will probably be the first to fail period. More than likely it won't be because the fan stops spinning, it will be because the bearing is failing and all the sudden the fans are 4x louder.
So yeah, don't use corrosion inhibitors and a couple years, do use corrosion inhibitors and last a LONG time.
I dont use inhibitors and I have kit going on 7-8 years old,still in use and still as good. Not a bad thing to have in a loop but not make or break by any means.
OP- Basically you get what you pay for,skimp on something and it will need replacing sooner rather than later. A high quality pump should be top of your list,anything with a moving part is prone to wear and you should spend a little extra on these components.
Also,fan controllers...if you are getting one,are mostly junk unless you spend money,the cheap ones are cheap for a good reason....they are garbage. Edited by B NEGATIVE - 4/5/14 at 12:18am
