It. 3 years ago Why can't I just place it at the back of the heatsink exhausting towards the rear? You don't want to blow dust from the outside into the case. 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. So...let's recap...there is sufficient distance between cpu and heat sink and the heat accumulated inside the heat sink is blown (spread) away via the channels of the heat sink. Also, fill up any holes besides the fan, because otherwise it won't work as well. But for the stock fan for the Ashura heatsink, the arrow points in the direction of the logo. What direction should the heatsink fan face? Get your answers by asking now.

This is where the exhaust fan (s) will take over, dragging this warmer air out of the case. 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. How do I make sure the EHD is detected. I just want to know what is the best way to dissipate heat from the chip. Air Should Flow from Front-to-Back, and Bottom-to-Top When mounting case fans, air flows across the open side towards the side with the protective grille, like so: So the open side of the fan should face outside the case for intake fans on the front or the bottom, and it should face inside the case for fans on the rear or top. And it depends on fan construction. I fix computers on a daily basis. 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. dangerden also recommends pulling out and they're radiators are very similiar to swiftechs.

By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. There are many cooling variations but arguably the most common approach will be to have: Rear Exhaust Fax <--- Heatsink <----- CPU Fan. When done correctly the CPU should remain seated in the socket. That is the reason why the heat sink has a thermal paste underneath it as well. On the 2 pictures you linked to, those fans are blowing the air towards the rear of the case. Asking for help, clarification, or responding to other answers. It doesn't matter what side of the heatsink the fan is on, as long as the fan is blowing the hot air out the back/top of the case. It's the same principle here. This is where the exhaust fan(s) will take over, dragging this warmer air out of the case. Pull the heat away from the heatsink and towards the exhaust fans. Make sure the front of your CPU fan is facing into the back of the heatsink, so it is pushing cooler air between the blades of the HS and out to the rear. There are two types of air flows to cool the heat sink: If the surface to be cooled is small and also has limited air input to its surface used induced cooling. Which way should I point my CPU cooler fan to get the. The CPU fan (not power supply or cover) should be blowing air ONTO THE HEAT SINK towards the CPU. If your PC case has a vent on the bottom for your PSU intake fan, and you’ve installed the PSU with the fan facing downwards, you should take some extra steps to help ensure proper airflow. Which direction should cpu cooler fan face. However, on several review sites, I've seen the fan face the opposite direction (and quite a lot of googled images): The fan in the second image (same heatsink, same fan) blows towards the front of the case, Think of it this way, if you have all other fans cycling air through your system (cold air from the front bottom fan(s), and hot air leaving through the top fans) and your CPU fan pushing heat onto your heatsink, you're pulling the warm air into the heatsink, thereby reducing its efficiency at doing its job. Why was there a "point of no return" in the Chernobyl series that ended in the meltdown? Most won't let you mount it facing any other way anyway O-o. Additional information. Whoever tells you that the fan should be blowing ONTO the heatsink is a fool.

If in doubt about the direction of air flow through your CPU fan, apart from the labels and markings it may have, you should be able to figure out from the direction of rotation which way the air is going. What kind of tape do I need to tape cpu fan to heatsink in notebook? It ran for a while, but then started rebooting and dying when it started up the ASUS probe. The fan should face away from the CPU. 36 minutes ago The cpu cooler fan should face towards the back (exhaust) but should push air through the metal, not pull through....unless it's a dual fan cooler level 1 Some CPU fans have 2 pins while others have 3 or 4 pins. What's the best time complexity of a queue that supports extracting the minimum? Front fan already installed flowing in, PSU fans blowing out.

Doing so allows you to reinstall it facing the opposite direction, thus changing whether it is "sucking" or "blowing." Air gets sucked in from the front of the fan and exhausted out the back. Thus. The heatsink dissipates the heat produced by the CPU. Rear fan <---Heatsink <----- Heatsink fan The fan should face away from the CPU. If your case flows the heat from front to back , then the heat leaving your CPU should probably also flow out the back.

It is always our recommendation that you buy cases with a minimum of 3 fans (or at least slots for adding them yourself) for gaming systems, not counting the power supply, CPU, and GPU fans. 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. I'll be getting the new Q9450 from Intel that includes a heatsink and fan, but may replace it with a 3rd party product. PostGIS Voronoi Polygons with extend_to parameter. The fan life diminishes drastically with temperature, so why expose it to the hot air exiting the heatsink (like in the "sucking" placement?

While the heatsink also releases heat, the fan is there to assist by blowing the hot air away from the heatsink-fan assembly. Airflow through the case is important, so yes, it matters. 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 … If I knock down this building, how many other buildings do I knock down as well? If not, it isnt a great case for heavy computer builds. There are other good reasons to flow from front to back, like the hard drives and ram do not get heated by the cpu and gpu.

Thanks for contributing an answer to Super User! Heaving said that....it is ILOGIC to blown away air facing the opposite of the heat sink in VAIN. It should be blowing away from the CPU. Besides the cooling performance there is also protecting the fan from higher temperatures. Your CLC at 55% is making a little louder than a top tier cooler at 100% .. and most of us on air rarely run above about 70% (1000-1100rpm @100% CPU load @ 60-65c depending on CPU, overclock, case fans & cooler being used). Also, the even distribution of air allows all of the chips and circuits to get cooler, fresh air, not just one spot. Assuming a tower type, you want the fan to blow in the up direction. Do: Mount the fans pushing in a direction where hot air can travel freely (Straight up or to the side). Or slightly warmer CPU, but maintain a cool motherboard and GPU.

Traditional CPU coolers face towards the left side panel, meaning the fan sucks air to cool the heatsink. When you suck air, its pressure is lowered, resulting in fewer molecules of air to absorb and carry away the heat. This will probably be appropriate for you. how to fix a non-existent executable path causing "ubuntu internal error"?
