If you’re one of the many PC gamers out there that uses an AIO or closed-loop cooler to chill the CPU, you’ve almost certainly got a product that licences one of Asetek’s designs. That company pretty much rules the roost when it comes to AIOs, so when somebody else comes up with a different design, you can bet that they’re going to be very protective of it. This is why Cooler Master’s lawsuit against three other cooler manufacturers isn’t in the least bit surprising.
Cooler Master is claiming Apaltek’s designs violate three of its patents that cover overall design, water pumps embedded in the radiator, and an ARGB lighting controller. Some or all of these aspects feature in a significant number of SilverStone and Enermax AIO coolers but Apaltek also does the same for the likes of MSI. As to why CM is only targeting two specific vendors, and not all of them, isn’t clear but it’s probably because they’re far smaller companies than MSI, et al.
Naturally, Apaltek isn’t happy about this and contacted TechPowerUp with a comment recalling that Cooler Master itself was at the receiving end ofan Asetek lawsuit six years ago, though that was a case which ultimately went in CM’s favour. Apaltek went as far as to label CM’s behaviour as being that of a ‘bully’ but if its patents have genuinely been violated, you would hardly expect them to sit around and do nothing about it.
Especially sinceAsetek’s designs dominate the AIO cooler market. If your cooler has a pump that’s part of the CPU’s heatsink block, it’s an Asetek one. So trying to come up with a cooler design that won’t incur the wrath of its lawyers is quite a challenge, hence why Cooler Master is being pretty vigorous in its claims.
If the lawsuit is successful, then the three defendants will be required to pay damages and legal costs, though it’s not clear at this stage just how much relief Cooler Master’s lawyers will plead for. I can’t imagine that it will be a small amount, but even if CM wins it case, it’s unlikely to receive the full amount demanded.
Whatever happens, this certainly won’t be the last episode in the seemingly never ending Cooler Wars saga.
