That's mostly FUD perpetuated by UPS manufacturers. Quick note: You don't need a pure sine wave UPS for _modern_ PSUs. Just curious how yours is performing and if you have checked your temps lately if you are still using this Enermax Liquid Cooler 240 unit. One video suggested to use the Mayham X1 Eco coolant as it had no glycol in it, but did contain antibacterial, anti fungal and anti corrosion additives, so I may give that a shot as it is supposed to work with aluminum radiators as well. Since it has an Aluminum Radiator and the Copper Plate, I have to be careful about using certain coolants as to not cause a metal corrosion problem. Now I have to find some new coolant for this unit. So, for now, I installed the stock Intel fan cooler and things are much better. After watching others that have these AIO coolers as well as other brands, I discovered that these things tend to lose coolant over time and also get crud in them that blocks up the micro fins on the inside of the pump copper cooling plate which blocks the flow of coolant through the pump.
COOLER MASTER HYPER 212 EVO REVIEW 2015 FULL
Funny that the fans were running full blast, but very little to any heat coming out of them.

At one point, I was doing a video conversion on handbrake, and yeah, the system just froze up. When viewing the temps on the core's and block, I found that under a heavy load, the temp was rising up near and some cases over 200 F which is not good. Now, March 2022, I noticed my PC intermittently locking up which it never did, and I also noticed that the fans either ran idle speed or almost full blast when doing very light work or watching youtube videos.

How is your Enermax LiqTech 240 cooler working these days? I bought one of these back about the same time this video was created (March 2015), and it has run almost non stop since then.
