Do I really need a computer case fan?
The newer cases usually comes with few case fans, so if you’re just a regular PC user, you’ll be more than fine. It hugely depends on the tasks you’re planning to perform on your PC.For instance, if you’re a professional who is using a PC to do 3D modeling or extreme graphic design, you must be aware of the fact that your system will heat over time. More heat means less performance which in result, decrease the lifetime of your components.Having a case fan is such small investment of time and money, but it gives your components, and system in general, better performance and longer lifetime. I wouldn’t think a second when it comes to heat control of my system.The thing is that you probably don’t want noisy fans and you’d like to have a control over the speed. My advice is to buy the larger fan that can fit in your PC as it will have lower RPM to produce the same temperature smaller fan will need. Also, the majority of these fans comes with controllers which gives you a complete control when it comes to adjusting the RPM.For instance, if you’re not working on something demanding for your components, you can easily slow down the fan to lower the noise.Here you can read about the features you need to look for when getting a new PC fan.
Lubricating intel cpu fan?
Recently I lubricated my pentium 4 CPU fan with a sewing machine oil (Singer brand). I did this because I thought this fan was the source of noise in my pc, but I was wrong! Actually the noise was from the PSU fan, so supposedly my intel CPU fan is in good condition... I peeled the intel sticker halfway and applied some oil in the hole at the center. Then I put the sticker back, but it didn't stick back as before (the edges didn't stick firmly to the fan, but the hole at the center is covered). Is it bad? Should I straighten it with some tape? I learned that oiling method from some webs, but all of them use some fan other than intel's fan. Also, someone said to me that intel CPU fans rarely need any lubrication. So, did I actually do something I shouldn't? Is it bad for my intel fan? Any side effects? If it is bad, what should I do? (My pc is 8 years old and runs 16 hours everyday, sometimes it even runs 24/7) Thanks in advance!
What's the difference between "CPU FAN" socket, "CPU OPT" socket, and a "SYS FAN" socket on motherboard?
Question:What's the difference between "CPU FAN" socket, "CPU OPT" socket, and a "SYS FAN" socket on motherboard?The CPU FAN header is exactly what it says. A typical PC would have a single CPU and a heatsink mounted on top of it with a fan. That is where you would plug in the fan. The reason why that header is important is because it will detect whether your fan is running are not. If it detects the fan is not running or not running properly, it will shut down your system (or refused to start your system) to protect your CPU from overheating.The CPU OPT stands for CPU optional. Typically, this is the header that you would use to connect some type of wiring for a liquid cooling system. For example, I have two pumps running my liquid cooling (two separate loops). Each one of these pumps has a single wire that I can plug into the CPU OPT header. Although I don’t use this feature because I want my cooling pumps to run at full speed. However if I decided to plug those connectors into the motherboard, it would probably allow me to control the speed of the pumps from the motherboard which brings me back to the CPU FAN.Most gaming motherboards will allow you to control the speed of the heatsink fan that is connected to the CPU FAN header. The reason for this is that if you are not using the computer under heavy load, you can reduce the speed of the fan and therefore reduce the amount of noise coming from your system.There is more than one name for SYS FAN. Asus refers to them as chassis fans or CHA-FAN. I have heard of other motherboards refer to them as case fans. Regardless of what name you call it, these are the headers you use to plug in the fans that are used to cool your enclosure or case.As motherboards become more sophisticated, the headers on the motherboard take on more specialization. I just recently purchased the latest 270 motherboard, an Asus Maximus IX Formula. In addition to CPU_FAN, CPU_OPT, and 3 CHA_FAN headers, it also has the following:You will notice that all of the headers are 12 W and 1 A except for the W_PUMP+ and the H_AMP which are 36 W and 3 A. You can control the speed of all of them from the motherboard except for the AIO_PUMP+ and the W_PUMP+.
What happens when you remove the CPU fan from a dekstop computer?
i have a cpu which i use sometimes. I want to remove its fan. Not the processor's fan but the one which cools the whole cpu which is normally located at the top of the back of a cpu. So anyway what happens if i cut the cpu fan's wires and take the fan? Can i still use the computer? I can't buy a cpu fan. So i want to take it from MY computer.
Cpu Fan doesent fit on Micro-BTX motherboard, Why?
Well, even if they both had the same socket type; it doesn't mean that the CPU will work, or the fan, or the powersupply etc. etc. I mean, for example; you get a Shuttle PC (those cubic ones) even though they may have the same CPU socket number, you may not be able to use the high end CPU (of that socket) Because the CPU will overheat, the motherboard is not compatible with Dual-Core etc. Anyways, I've got a 120mm CPU fan that only goes on specific model of heatsinks. You'd think 120mm is a 120mm and should work with any heatsinks of that size but nope... And not to mention when I had liquid glycol cooling in there... I removed the liquid/water cooling and tried to attach a regular/air cooling socket fan... well, the OEM guys had removed the original CPU heatsink mount from the motherboard (little plastic and some screws that you won't find in stores unless you buy the motherboard) If it doesn't fit without you modding the screw holes etc. don't use it... trust me on this... just go out and spend $30~, and get the one that fits... Do you know what happens when your CPU fan falls off of the heatsink when the PC is ON? A damaged CPU is the least of your worries... Again, if it doesn't look like it will fit (screw holes are further part) DO NOT use it. I have had a $8000 loss when my heatsink fell off. (No fan since it was water cooling.) First the CPU got cooked, then the pipes started to melt/expand, then it sprayed water/liquid glycol non-conductive luckly but spilled slimy liquid all over the components then the fallen CPU heatsink destroyed my RAID card (I was running RAID-0) on top of that broke the SATA pin on one of two hard drives which rendered the entire RAID array useless, so there is no way to recover the data on those drives, and only thing that still worked was the RAM and the optical drives. Everything else was DEAD... All because somebody didn't tightened the screws hard enough. Don't bother trying to mod that fan on it, if the fan fell off while you were a sleep (or while I was on vacation in my case... It was dumb of me...) Remember that the fan will still be spinning which can shread the chips on your Motherboard in pieces and your CPU will start to overheat (most modern processors will shutdown but some won't...) BUY NEW FANS.
Is rear exhaust better or top exhaust (in a PC)? I have 1 fan for exhaust, and I’m not sure if I place it in the rear or at the top.
It’s not just about hot air going out, it’s also about where the cold air comes in.If you put your exhaust fan too close to the inlet grill, there will be localised circulation of warm air being sucked back into the machine.Side intakes, with tubes or ducts that take air directly onto the proccessor heat exchanger are useful, but beware of having them too close to the wall, or the upright of a desk, we have had many clients that complain of computers overheating because of this.You want your computer tobe getting the best colder air possible, so if you can, keep the intake and the exhaust as far away from each other as possible.Ideally, the intake, (with a fine filter) on the bottom benefitting from the ground cold, unless you have underfloor heating… and the exhaust on top, with as mentioned a pretty fan…This way the heat is behaving as it should, rising. Whatever you custom build, you should think about having thin filters on the inputs, I use ladies nylons cut into disks and screwed in with the catch plate, they don’t interfere much with the airflow, but stop a looot of dust.It’s not really heat that kills a computer, until the build up of dust causes that heat to rise.Now;- for the “uber” builder, you have to think about the hottest points on the set up.This is the proccessor, and the graphics proccessor, followed by the north and south bridge chips, that quite often have cooling fans of their own.Your graphics card has a fan on it, and everybody is blowing in a different direction, oh woe..Luckily, normally computers are pretty robust and designed to cope with all of this, but not when you start moving bits around.So you can build your own ducts if you want that get all of the airflows going the same way, up and out the top. Logic.Unless, you have a computer that is lying down, oh dear. What you need then is the upper side of the computer to be perforated, with either a big fan, or multiple fans.The computer lying down would probably cause me to have the air coming in from the top, and being thrown out the rear and origanal bottom of the case.Bigger fans, does not neccessarily mean better cooling if they are not blowing in the right direction.All of this gets to be a lot more fun if you start playing with water cooling as well.There is also teh proximity of the power supply exhaust to think about.Overall, unless you are custom building, it doesn’t really matter, as the margins are wide.
PC Crashing or CPU overheating?
Hi! I have just recently built a PC. My specs are a XFX R9 280, 12GB's of RAM, AMD FX-8350, Gigabyte GA-970A-D3P Motherboard, 500w PSU, and a BitFenix Comrade Mid Tower ATX Case. Just recently it has started freezing while in any game after an hour or so, I go to feel the top of the case (which is where my CPU is near and a exhaust fan) and it is extremely hot. So I stopped using it for about a week and put in a stronger exhaust fan and 2 120mm intake fans at the front of the case and it still freezes. I have a feeling it is the CPU. I tested the temps while idle (with Skype open) and the temps were 60°C at idle. While I was playing a game I went to go check my temps and they were 72°C and kept on playing and it froze. I felt the top of my case again and it was blistering hot. I've heard that I should get a after market cooler like a Hyper 212 Evo but I don't know if it is the CPU for sure. Please help!
What is the cheapest fan I can buy for the GPU, and is it one size fits all? If not, can you give me a link to a certain fan I could use?
Your GPU already has two fans, and RTX 2080 builds I’ve seen already have good cooling. Your GPU cooling upgrade would be to a water block, not another fan on the GPU. However, it looks like there are some major cooling improvements you could make to that case:Looking at your system in the link: there’s a rear fan (assuming it’s blowing out), there’s a CPU fan blowing toward the MB, and two fans on the GPU likely blowing toward the fins that direct air out of the back. There’s a PSU fan, likely blowing out, and no intake fans.A major potential cooling issue with that case is air intake. It looks like there’s a very small air intake opening on one side by the the front panel.EDIT: Upon looking on HP’s site, there are no intake fans. Rest of answer deleted as irrelevant.
