Sealed all in one coolers are one of the biggest sellers in the PC cooling industry however they have a massive downside and that is there life span. This were custom cooling or OAIO’s (open all in one) is much better and simply put, over a long period of time works out cheaper if done correctly.
The main reason for SAIO’s (sealed all in one) coolers to fail is there usage of glycols in there coolants, these glycols are present in high ratios (% of glycol to water / carrier fluid) making them less thermally efficient but also they cause a secondary issue. The second issue is that glycols when heated up over a period of time becomes thicker and this in turn wreaks havoc on their small internal pumps. Eventually these pumps fail not because of usage but because they simply cannot handle the viscosity of glycols when they thicken up. When using a custom cooling loop or an OAIO you can easily and frequently replace there coolants and refresh the system negating this issue of glycols getting thicker.
Reviewers of AIO’s never look for the long term effects of such systems and never inform uneducated users of such issues. Like an old saying measure twice cut once, well "think twice buy once!"
