I wonder why it is acrylic is still being used for liquid cooling. It has a temperature limit of like 50-55C and will visibly crack and or warp at them temperatures. Not to mention failure of any sort is awfully close at them temperatures as well, albeit from hairline cracks and or just one off in the production process. With liquid temps never going above 45 degrees ever I've still had acrylic rear up its ugly face and fail. POM Acetal on the other hand i can guarantee will not crack and or warp. Hence I've learned my hard lesson first hand. triple Acrylic lian li pump top from XSPC failed on my three separate times...So i bought my POM Acetal BitsPower pump tops X3 for all of my pumps and placed them in a series just like they were with the XSPC and viola no leaks and no pressure issues!!! Especially if one is going to be spending hundreds of dollars on a "few" of something I personally would love longevity from it. POM Acetal FTW... Acrylic is so yesteryear.

well that's somewhat worrying to find out but thankfully i've never experienced any cracking of my cpu/gpu block or reservoir tube. my old liquid cooling could at times reach 53 degree's water temp new one hasn't reached above 46 in the summer yet and should be getting even cooler with an upcomming case switch (NZXT H440 > Lian Li 011 Dynamic).
