Prof Aronnax Just saw this thread. I am no expert, but there are long threads here about clouding and "plasticizer", which, as far as I can determine, is an element in some tubing getting leached out due to an unknown combination of chemicals, pH, and gremlins. I'd suggest searching the forums with that term.

brenchen Bump... Anyone got any ideas on the cloudiness of the water?

brenchen Now the kit is set up (finally went for XSPC EX360 with push-pull, although only has the push for now, the pull fans are still sitting in its box).

I noticed the water in my clear tubing is getting a little cloudy. I've put in a silver coil and some additives for the water, and washed each component before I put it together. Would this cloudy problem be normal? Or did I mess something up?

Martinm210 I have mixed fans without a problem. It is really no different than have unmatched intake vs exhaust case fans. Air compresses and sure there is some minor speed up in push pull, but i have yet to see where mixing fans is harmful. I suppose if you put a 5000rpm delta behind a 500rpm fan you might see something entertaining, but not a few hundred RPM. I think I tried 3000rpm UK3s with yate loons one time and still didn't see any problems. When we are fighting against resistance the blade is slipping if you want to think of it that way. We usually see less than half of max air flow. Two fans in push pull can increase that by 20-30%, but it is still not the maximum flow of one fan in open air.

Anyhow, I haven't been able to find any historical example of where mixing fans is bad if you keep them roughly similar and I have tinkered with mixing some fairly extreme different fans and still got the same good result.

I just don't know. I've always just matched fans and especially fan speeds. It might very well work. I will have to defer to someone who has actually tried this.

Um, you might not want to do that.

The AP-15 fans run at 1850RPM. The XSPC fans that usually come with the kits are typically 1650RPM fans.

I personally would not put different speed fans on one side of the radiator as the other. It very well may not make any difference, but if it were me, when you buy the kit, just get 3 more XSPC fans and have all 6 running the same speed. That is what I did when I got my RayStorm D5 EX360 kit for one of my rigs.

The logic being, if you have a 1650RPM fan on one side pushing air through the radiator and the "pull" fan running at 1850RPM, the higher speed fan might get "starved" for air since the lower speed fan isn't likely to be pushing as much air as the higher speed fans desire. Likewise, if you have a higher speed fan pushing air to a lower speed fan, you could cause a minor pressure build up.

Again, it very well might not make any difference, but if anything, dissimilar fans might end up not being as quiet as similar fans as they are fighting each other with airflow.

Just my 2 cents.

brenchen Oh one more thing, how's the K2 thermal paste that comes with the kit? Or should I get something else instead?

Thanks for the summary, it's very good smile.gif

I think I will go for the EX kit (when they are back in stock) because I prefer the compression fittings, and the D5 which is an overkill now, but may need it some day.
