Removing the Top Front vent allowed the CPU cooler to intake fresh air, bringing a noticeable 2C drop in temperatures. Removing these should allow fresh air intake even without fans on them. The Define R4 has 3 vent covers: 2 on top, and one on the side panel. However, some of the triple fan coolers like the Powercolor PCS+ and Sapphire Tri-X and Vapor-X may be able to intake air from the rear. Since the GPU I'm using doesn't have fans that sit that close to the rear of the case, the fans don't intake air from there. Supposedly, removing these covers allows the GPU to intake air from the rear, reducing GPU temps. Because of this good result.ĪLL TESTS BEYOND THIS POINT WILL HAVE NO DRIVE CAGES.įor reference to these new tests results, here's the control temperatures.
Multi GPU setups may see a benefit from removing all cages since the bottom fan can move air towards the bottom GPU. Removing the bottom drive cage brings no benefit since the top is already bringing fresh air. Hard Drive Cage (12V Fans)Īs you can see, removing the top drive cages brings an instant 3C benefit. By doing this, you unblock airflow that's going towards the GPU and CPU. One of the easiest ways to improve airflow is by removing the drive cages. Visual diagram of part placement and airflow. Note 4: All tests (except the PCI slot cover test) run with both stress tests on. Expect a larger gap between good and bad temperatures if you do not have a flow-focusing fan. Note 3: The Noctua NF-F is a powerful, flow-focusing fan. This gives off less heat than stressing the FPU with it, but since I run quite a high overclock, the temperature difference is enough to cause my system to throttle. Note 2: AIDA64 CPU and Cache stress testing was used. It ejects heat out in front and out the sides of the graphics card. Note 1: The Sapphire 7970 Dual-X is an axial cooler.

The reason is because it allows for a slight positive pressure setup and is a reasonable number of fans for cases to have (2 intake, 1 exhaust).Īnother reason is because I don't have enough of the same fan to test configurations with different numbers of fans. Backgroundīefore we start, let me clarify that I will use 3 fans all of the time. Some configurations are quite obvious, while others are quite oddball. But just how effective is it? These tests aim to see what configurations offer better airflow as discovering why it acts the way it does. Pick, Assemble and Install: Video GuideĬases nowadays come with ways to mount fans in different locations, open up vents, and clear a path for airflow.No intentionally harmful, misleading or joke advice.No excessive posting (more than one submission in 24 hours).No selling, trading or requests for valuation.No self-promotion, advertising, begging, or surveys.No submissions about memes, jokes, meta, or hypothetical / dream builds.No titles that are all-caps, clickbait, PSAs, pro-tips or contain emoji.No submissions about retailer or customer service experiences.No submissions about sales, deals or unauthorized giveaways.No submissions about hardware news, rumors, or reviews.Please keep in mind that we are here to help you build a computer, not to build it for you.
