";s:4:"text";s:4888:"Hello, I wanted to ask which way should the fans face on my water cooler? Most people opt for a more balanced approach, leaning slightly toward negative air pressure (for theoretical cooling) or positive air pressure (for less dust buildup), and we’d probably recommend something in the middle there. You want at least one intake and one exhaust fan at the very least, so assuming you have more, which is better, drawing in more air for positive pressure or blowing more out for negative pressure? In reality, PC cases are so far from being a sealed environment that the difference is probably negligible. But for the sake of completeness: water cooled components have a minimal effect on the internal airflow of a case. You don't want to blow dust from the outside into the case. Clean them out with water and dry them completely every few months to keep dust from flowing into your case (again, slightly positive air pressure can help here too). Every six months or so, or more often if you live in a particularly dusty area, open up your computer and blow it out with some compressed air to get rid of any lingering dust. Why is that so? Cables, especially the large bundled rails from a power supply, can be especially troublesome. So I just used 8gb ram for ⦠Since the inside of the case is usually quite warm indeed, this isn’t really a problem, but if you use the PC in a particularly hot room (like an un-air-conditioned garage in the summer) you’ll see less effective cooling. … If I place my fan like this, will it improve airflow? If you’re purely concerned with temperatures, check CPU and GPU temps with a software monitor and try some different configurations. If possible, mount your radiator and fans as exhaust fans. that it just ⦠A heat sink on the processor or any other internal cooling unit, can suck or blow depending on the make of the heat sink and configuration of the computer's interior components. So why don't I simply direct it towards the rear fan instead of pushing it back to the front? On the other hand, blowing the air increases its pressure, thus increasing the number of air molecules and their ability to carry away heat energy. Depends on the chassis your using.. Assuming all the fans are the same size and speed, then you have one of three possible options for the air pressure inside the case: Because of the way the internal components create blocks in airflow, it’s more or less impossible to achieve a truly equal air pressure inside a case. Check your PC for dust buildup regularly. Here’s a really nice example of a case with good cable management creating open airflow. I bought an Antec 120 mm LED fan to use as rear exhaust. Do not mount exhaust fans on the bottom of the case; since hot air rises, a bottom-firing exhaust fan will be working against physics by expelling slightly cooler air instead of warmer air. Side-mounted fans can be intake or exhaust, depending on the setup. (max 2 MiB). The direction a fan blows air is always determined by (A) the shape of the blades (sometimes called propellers) and (B) the direction they turn. But for the stock fan for the Ashura heatsink, the arrow points in the direction of the logo. Get as many of these cables out of the way as you can. The CPU coolers should blow towards the back exhaust fan. Some flow designs have exhaust out the top, they may choose to send the cpu heat more foreward to be pulled out by top fans. Before you begin, you’ll want to look at your available fan mounts and decide the best way to plan out your airflow. Which direction should cpu cooler fan face. And the logo is in front in both my setup and the second picture. It is common sense that a CPU cooler with tower heatsink must be installed with its fan pulling air from the front of the case, blowing in direction of the rear of the case. It should have depended on the actual air movement which on a lot of fans is not center at all, the hub is in the way , and much of the movement of air is at the ends of the fins. When I put the heatsink and fan from the machine that had the dead cpu, I started having problems - I thought it was because of the shroud and a couple of sites said the air should be taken out from the cpu. To diagnose the CPU usage issues, you should use Event Tracing for Windows (ETW) to capture CPU Sampling data / Profile. Welcome to the forums by the way! Close the latch to secure the CPU. Ideally, you want to place an exhaust fan as close to the CPU as possible to quickly expel this hot air. Othewise you can either look at the blades, the shape is different on front and back, or simply try to power it on. There are people who have chosen to have the hot air blow forward in a case, because they like the heat to land there (warmth), They had cooler air behind the case, or they just wanted to be different.
