Check System Fan Error

3, 2014] If you replaced the system or CPU fans, or moved the hardware contents of your HP computer to a new case, you might be getting an "F2 fan error" on

boot. Thankfully there seems to be a solution. After I upgraded my computer to system fan error press f2 to continue a new case I started getting the following error during startup/reboot: Error: System Fan Has Failed! Service PC to prevent damage
System Fan Error 90b
to the system. Press F2 to continue. The case I am using has two stock fans on the back, and I replaced the stock CPU heasink and fan with a Cooler Master Hyper heatsink/fan combo. The system fan 90b error message on startup system originally came with a 3-pin CPU fan that was connected to a slot labeled on the motherboard as "SYS_FAN1," but the new CPU fan that came with the over-sized heat sink has a 4-pin connector that I plugged in into the slot marked as "CPU_FAN". From what I can tell the SYS_FAN1 slot monitors the fan speed, so it had been asking me for the system fan ever since because there's nothing connected to that computer fan error 3-pin slot. Before continuing, please note that if you haven't changed any parts and you suddenly started getting that message, then make sure the fans are really working. You don't have to change the settings if all you need is to replace a fan, so make sure you check your motherboard's fans configuration to try to isolate the problem. Also, if you did change fans, then you can always reconnect the old fan or a new fan or equal size and speed to the SYSFAN slot. If none of that works, or you just don't want to deal with that message, then continue reading. Pretty much every computer troubleshooting forum or website tells you to go into BIOS and look for "Hardware Monitor" and disable the one that's causing you problems. The problem is that, for most HP computers, that option is hidden. After months of looking and finding the same guides over and over again, I finally found the right answer. I re-wrote it to what I think is easier to understand. There are two ways to go about this: Boot your system and press the F11 key when HP splash screen shows up. The F2 error will probably still show up, so keep pressing F11 repeatedly until it gets passed it

reported. Hey anyone who can help, I recently put together my first computer mostly on my own dell fan error (A tech-savvy friend came over to make sure everything was plugged in right). Every time I boot up the computer, I see the error message "CPU Fan

Error", but when I look at the fan, it's most definitely spinning away. Certain programs (mostly large games like Diablo 3 and Dragon Age) will crash the program shortly after starting up, if not crashing the entire computer, and many smaller programs will freeze http://retrohelix.com/2012/09/how-to-fix-the-f2-system-fan-error-on-some-hp-computers/ or close on their own, which I have been told may be a sign of overheating. I've tried restarting the computer a number of times, uninstalling the games, plugging the fan into different ports on the motherboard (in case I had it wrong), and even bought a new fan, and I still keep getting this message. I've had this new computer for around a week now and it has been nothing but trouble. All I want is for it to work. Can someone please help me?

Welcome to HTG sadieb, Try downloading "SpeedFan" to see what your computers temperature is at. The way to find it is to click configure once installed. Temps will then be given. Post back what the temp is usually around (ex: if it goes from like 18 to 20 to 19 to 20, just say like 20). Reports: · Posted 4 years ago Top sadieb Posts: 3 This post has been reported. According to the BIOS menu when I booted up, the CPU was sitting at around 34. As of right now, it's around 39-40. I also keep getting error messages saying that "windows explorer is not responding" every few seconds, at which point my desktop, start menu, and toolbar all reset, until finally they decide to just close instead of restarting (All that appears on my desktop is the background. No icons, no toolbar, no start menu) Reports: · Posted 4 years ago Top Xhi Posts: 6298 This post has been reported. Your fan may be running, but not at full speed which it may require. Are you absolutely sure that the CPU fan is plugged into the receptacle on the motherboard that is marked CPU Fan? Double check. The resetting of your desktop is due to Explorer.exe crashing. Not sure if the two events are related. If this is a purchased computer, rather than a build, I would take advantage of any warranties that may apply very soon. Even with a build I might take advan

Personal QuestionWhen I boot up my PC this error "CPU fan has failed" is shown. What could be the possible problem?UpdateCancelAnswer Wiki7 Answers Leonid S. Knyshov, I run a data recovery companyWritten 82w agoWhen the CPU fan fails to report rotational speed above the threshold of failure to the motherboard, the motherboard will alert you by saying that the CPU fan has failedOn a desktop, the CPU fan connects to your motherboard with a 4-pin (older technology and some aftermarket fans use 3 pins) power connector. There are temperature sensors on the motherboard. There are also usually multiple 3-pin (they are sometimes 4-pin) headers (groups of multiple pins with a plastic "key" to ensure correct orientation of the connector) into which the fans get plugged in. Laptops have a similar arrangement, but they may use non-standard connectors.On this example board, the CPU fan is connected into the 4-pin header and there is another 3-pin header next to it.While operating properly, the CPU fan reports back to the motherboard its current rotational speed. The motherboard regulates the speed of that fan according to the temperature reported by the CPU temperature sensor. If that speed is too low or missing, the motherboard will say the fan has failed.You can simulate this failure by unplugging the fan from CPU header and connecting it to any other fan header, like Case Fan. It will still spin, but your motherboard will complain because it will think there is no CPU fan attached.Others explained how to solve the problem. Do not run a computer without a CPU fan even for a second. Use a thermal compound to improve heat transfer efficiency. The cooler your CPU operates, the happier your computer feels.4k Views · View Upvotes · Answer requested by Andrew GutschRelated QuestionsMore Answers BelowWhat is the best way to check if my laptop is failing due to the CPU/GPU or a fan problem?What can I do if my CPU's fan runs and then stops but it does not boot up?What exactly do Microsoft Windows 7 Boot Repair do to repa
