Rosewill RCX-Z4 CPU Heatsink Review


The Will of the Rose

There I was. Standing there in nothing but my underwear. She comes in with a roll of bubble wrap and a box set of the new season of Scrubs. This has nothing to do with this review, I am just really cool like that and my fantasies are awesome.

Speaking of cool. It’s time for yet another review on the long…. long line of heatsink/fan combos that are gracing the store shelves these days. Today’s victim, er, subject is the Rosewill RCX-Z4.

Now, I know what you’re all thinking. Who the hell is Rosewill and why should we care? The answer to both of those questions is this; I don’t know. Before I received my latest shipment of reviewee’s I had never heard of Rosewill. All I know is that they make one strange looking heatsink that in my opinion doesn’t look like it would do much at all. But my opinion only matters at the end of reviews and in horseshoes.

Here’s what I found out about Rosewill. They are a relatively new company looking to make a name for themselves. They currently sell over one hundred products through various online stores such as the big kahuna and, and their popularity is growing.

A few years ago they made a market attempt with ATI based video cards, but that soon fizzled out and apparently got scraped in favor of heatsinks. And rumor has it they are expanding into the NAS server market also. These guys are really going for it, aren’t they?

As I said earlier, todays test subject is the Rosewill RCX-Z4. It’s a freakish sort of heatsink, kind of reminds me of something out of an H.P. Lovecraft short, and without a doubt looks like it would take up a lot of space and possibly block access to several things. This very well could be my first pain in the ass since prison. Here are the specs on the Z4:
