ID-Cooling really should be considered for any of your SFF needs, they have bought out some great products. And these coolers really took me by surprise, for the price? You certainly get huge amounts of performance, but not only that. Id-cooling have bought out these coolers built for function. By this I mean they perform incredibly well in the scenarios that they will be used. Sometimes products can be over engineered and veer away from what I’d consider crucial design points. Both of these coolers keep temperatures within reasonable levels however the IS-60 provides near silence, and the IS-40 provides great cooling in situations that require the finesse of a smaller cooler. There isn’t much more I can say, other than it was enjoyable to see such great products for such a low cost. I wanted to review these together as they are really opposite ends of the SFF cooler spectrum, one is designed to be small. And the other is a large cooler designed for quiet operating. It’s a nice comparison to show you the difference, and if it was my money. I’d consider either of them depending on the case.
