Some of the best CPU coolers are all-in-one liquid cooling units, and while generally safe, there is always the risk (however minute) that something will go wrong. And something did go wrong on a batch of Corsair's Hydro Series H100i RGB Platinum SE (CW-9060041-WW) cooler, resulting in a partial recall.

"We discovered that less than 1 percent of Hydro Series H100i RGB PLATINUM SE coolers sold to date are leaking small amounts of coolant into the hose sleeving. These leaks are easy to spot, as the sleeving is white, and coolant is bright green," Corsair says.
