Thus. There are many cooling variations but arguably the most common approach will be to have: Rear Exhaust Fax <--- Heatsink <----- CPU Fan. In cases where the PSU is mounted at the bottom, the fan should face toward the bottom of the case if the case has vent holes in that location, otherwise the fan should face … A heat sink that is both active and passive blows air through the finned radiator to help the heat escape. so it goes: Heatsink -----> Heatsink Fan -----> Front of case. Coolest possible CPU, with somewhat warmer enclosure temp, thus slightly warmer GPU and motherboard. Hm, should've looked better at the packaging. Whoever tells you that the fan should be blowing ONTO the heatsink is a fool. My GLINK USB 2.0 extension cable isn't detecting External Hard Drive, though Pen drive is detected. here's one set of benchmarks, showing push (blow) does better than pull (suck): And someone else made it a science project, push wins again: That second article @Jeff linked is very confusing. Besides the cooling performance there is also protecting the fan from higher temperatures. It makes no rational sense to anybody having a basic understanding of heat transfer. And it depends on fan construction. Which direction should cpu cooler fan face. This is where the exhaust fan(s) will take over, dragging this warmer air out of the case. Is the bullet train in China typically cheaper than taking a domestic flight? They're just on the other side of the heatsink "pushing" the air instead of "pulling" it. I just want to know what is the best way to dissipate heat from the chip. 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. What factors promote honey's crystallisation? You want the coldest air possible being pushed or pulled through the heat exchanger for optimal convection-cooling. Of course, from my rudimentary understanding of physics, blowing makes more sense. If I knock down this building, how many other buildings do I knock down as well? The only time I got any improvement with the fan on the other side pulling air through, was when the same fan was ducted direct to the outside of the case, so the heat from the cpu was direct to the outside via that fan. There are three types of axial fans, tube-axial, vane-axial, and propellers, which can have blades optimized for performance in one or other direction. COOL is only 3 letters away from FOOL. By changing the direction a fan is mounted, it can act as either an intake or exhaust. Use proper fan positioning Air travels one way through a fan, in one side and out the other. And that does not even take into account the noise made by pump and/or water/air bubbles in a CLC. Why is that so? Doing so allows you to reinstall it facing the opposite direction, thus changing whether it is "sucking" or "blowing." So the results may vary. AMD FX8350 CPU - CoolerMaster Silencio 650 Case - New Water Cooling System. Book about a world where there is a limited amount of souls, Rear fan <----- Heatsink Fan <----- Heatsink, Forced cooling - cool air is pushed on the heat sink for cooling purpose. The fan should face away from the CPU. The case should have vents on the top. 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. Best to to have the fan pushing into the heatsink, so the air around it is cool. rev 2021.1.8.38287, The best answers are voted up and rise to the top, Super User works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us.

That is the reason why the heat sink has a thermal paste underneath it as well. 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. Making statements based on opinion; back them up with references or personal experience. I would test it again, but without testing, I would always pick blowing Into the heatsink. Asking for help, clarification, or responding to other answers. Rear fan <---Heatsink <----- Heatsink fan It only takes a minute to sign up.

In order to have the right fit, your replacement CPU fan will require to have the same number of pins as your current CPU fan. Heat rises, so if you blow it downwards, it wont really be removing hot air. Or slightly warmer CPU, but maintain a cool motherboard and GPU. Check the Number of Pins for the Replacement CPU Fan. It. From what your saying your flow arrangement isnt to the front, so like you I do not see any reason to send it towards the front, to just fight the flow and eventually head to the back anyway, turbulance has value :-) but exhausting the worst heat most directally out of the case is going to make the whole case cooler. Also, fill up any holes besides the fan, because otherwise it won't work as well. Which way should I point my CPU cooler fan to get the. What species is Adira represented as by the holo in S3E13?
