need asus cpu fan replacement
My neighbor's desktop computer ASUS Essentio Model CM6850 needs a cpu
fan, it's making a lot of noise and not spinning up to speed, sounds like a bad bearing, the fan is model AUB0812VH. How can I look up the part number for that exact item so I can replace the fan with a replacement the software will be able to monitor? I took a chance and bought a same model fan but with a brown instead of red wire (originals are blue black red yellow) and the machine wouldn't boot - it didn't detect the fan. Thank God I didn't blow the m/b. Any suggestions would be appreciated. |

Nothing special about that fan that I can see -- just a bog-standard 80mm 4-pin cooling fan which should be available from a dozen makers. Here is the exact item at Amazon: https://www.amazon.com/Delta-AUB0812.../dp/B00H0B3XS8 but there are similar items for 2/3 the price although scrimping on a cooling fan is probably a bad idea in most cases unless you know the maker well and trust them. |

Thank God I didn't blow the m/b. Any suggestions would be appreciated. How is the fan attached to the heatsink? Screws, hold-down wire bail, or what? Likely you can use a replacement fan of the same size. You can measure across the sides. Might be, for example, a 60mm fan (rather small) or the same size as a case fan (80mm) and even possible its a 120mm fan. I don't know what heatsink comes stock in that computer. https://www.youtube.com/watch?v=47xTpv0aNYM That video is for an Asus Essentio CM6870 so it's close to your model. At timemark 1:49, the author tilts the case so the view of the 80mm backpanel case fan is easy to see. It is bit smaller than the CPU fan so I'm guessing a 92mm on the CPU's heatsink. Could not see how the fan is held to the heatsink but probably via screws through the corner holes in the fan that dig into the fins of the heatsink. How much if your neighbor willing spend on a new CPU fan? The Noctua fans are pricey but they last are usually pretty quiet. I suspect the CPU header on the mobo is 4-pin so make sure the fan's connector matches (so you don't have to do a frankenjob). You want a fan designed for PWM (pulse width modulation) to change its rotational speed. I'm assuming the BIOS or a program (e.g., Speedfan) or software that came with the computer will change the fan's speed to keep it quiet until the load increases whereupon more airflow is needed. http://preview.tinyurl.com/y8pldu7r Instead of getting a cheapy $6 fan that won't last a year, the Noctua 92mm 4-pin PWM fan costs about $16 (http://tinyurl.com/y8pldu7r). https://www.newegg.com/Product/Produ...9SIAADY4B02739 That one will probably work but you'll have to look at how the fan is held to the heatsink. It is a low-profile fan so it is likely thinner than the stock fan which means it will fit. It's up to you if you want to attach a fan guard to the outside of the fan to make sure cables don't accidentally get into the blades. I'm pretty sure airflow through the fan is into the heatsink, not outward. Positive air pressure results in less dust accumulation. If there is a side-panel case fan, ensure both blow in the same direction. If you replace the heatsink with a vertical unit, direction isn't important as the air goes through the heatsink instead of smacking into the heatsink's base and shooting out the sides. Just match the airflow direction of the new fan with the old bad fan assuming the old fan was put in correctly for airflow through the case. When you have your neighbor's case open, you are going to expend a couple cans of compressed air to blow out the dust, right? Do it outside; else, all the dust goes into the run and back into the computer and anything else. When blowing out the dust, use an ear swab on the fan blades to dislodge the stuck-on filth. When blowing out the fans, use a finger on a blade or the hub, or stick an ear swab through a fan guard, to keep the fan from spinning when blowing through it. Is the mobo's CPU header a 4-pin connection? Was the new fan you got also a 4-pin connector? Did you check that you weren't off by a pin when attaching the connector to the header? It may difficult to reverse connector but it's not impossible: they polarizing guard on the one side can flex. You did get a PWM-capable replacement fan, right? https://allpinouts.org/pinouts/conne...cpu-4-pin-fan/ |

The fan attaches by pressing the holes in the corners into plastic pins until small snaps at each pin snap over the edge of the plastic fan housing to clasp it. Works great, fast dis/assembly. |

You could get it at half the price at Newegg; see: https://www.newegg.com/Product/Produ...9SIAAES6CM9290 (5% off by using the promo code SXDOOL5) Both Amazon and Newegg operate storefronts they sell to sellers. For both the Amazon and Newegg listing, some 3rd party is selling. The product does not come from Amazon or Newegg but through a storefront there. For the price of the Delta fan through Amazon, you could get a better Noctua fan through Newegg. It is cheaper at Newegg, and that item includes free standard shipping. Also, Newegg covers Marketplace sellers with Newegg's own guarantee (https://kb.newegg.com/Article/Index/12/3?id=1172). With Amazon, you only have the seller to resolve problems. Usually Amazon is more expensive even at the same product price because of shipping; however, this item claims free standard shipping, too. With Newegg cheaper on price on the same product, free shipping (to match the Amazon ad), and with Newegg's additional guarantee, I'd go with Newegg. That fan is even cheaper at eBay ($6.84) and also with free shipping; see http://tinyurl.com/ybezmxq8. eBay has their Buyer Protection. Since you were looking for a USA seller, I selected the option at eBay to list only USA seller locations. You might want to elect "Buy It Now" to eliminate any auctions that only take bids (which delays when you win the item and way too buyers are boobs that overprice their winning bid). In the meantime, you might want to blow the dust out of your neighbor's computer, including cleaning the fans how I mentioned. It's possible that crud is layered on the fan's blade which throws it out of balance, so it makes more noise. |

The fan attaches by pressing the holes in the corners into plastic pins until small snaps at each pin snap over the edge of the plastic fan housing to clasp it. Works great, fast dis/assembly. If you hadn't found an exact match, the fan catalog lists the fans in a given standard size as low, medium, high, ultra each with a different CFM (and noise) rating. And you try to replace a fan with a fan of the same class, at least, if you can figure out what it is. I have one Ultra here, which is 110CFM. It was an impulse buy at my electronics store, because it was so nicely constructed. I keep that one turned down, as at full speed, you couldn't sit next to it. That Ultra is all metal construction (metal blade, metal frame). Practical fans are low and medium. 30dBa is a decent threshold. If it's above 30dBa, you'll probably be able to hear it. Typical case fans are 35CFM. And there is actually a cooling equation for the computer total power, that tells you how many CFM the exhaust fan on your PC needs to be. The math might predict one or two 35CFM fans are needed for the back of the PC. So while you didn't get exposed to any details on this purchase exercise, there are a few if you need to shop for a generic solution. I replaced the fan on my CoolerMaster CPU heatsink with a Vantec Stealth, and that was mainly because the heatsink was really more than the poor CPU I bought needed. So I could go "down a notch" on fan speed for the replacement. My CPU fans here generally aren't set up for speed control, and they just run at some fixed speed for their entire lives. The Vantec Stealth is a three pin fan, and the third wire is RPM. And the RPM signal keeps the BIOS happy :-) if the RPM signal is missing from the CPU fan header, the BIOS may stop the machine on POST and seek to warn you about it. The four pin fan, the fourth signal is the speed control. You can use a three pin fan on a four pin header - that's what I did with the Vantec Stealth. The keying tab will guide either a three pin or four pin into place. By using the three pin, and not having a fourth pin, I have no speed control. But since a Stealth isn't all that loud, it doesn't really matter what speed it runs at, as far as noise is concerned. If I'd put the Ultra I bought on top of the CPU heatsink, now that I'd be able to hear. And the CPU would "operate at sub-zero" with that much fan on it :-) The Ultra fan draws 1 ampere of current when spinning, so it's a bit of a pig. To power the Ultra, I use a Molex power connector, rather than a 3 pin fan connector or similar. Once the current draw gets high enough on a fan, it's time to "think defensively" about power sources for it. While the motherboard manual has a section with a terse "current flow spec" for the headers, it's not always possible to decode exactly what they mean on those. The terse statement leaves a bit too much to the imagination. The motherboard fan connectors are not protected with fuses, and it's actually easy to burn out a fan header if you're not careful. If you do burn out the header power track (+12V), you can get adapter cables to bypass it, so it's not the end of the world. If I were to plug four Ultras into my current motherboard, I'd definitely blow the power track. And I don't even need to look up the numbers in the manual to guess at the outcome. A ballpark figure for a fan header is 350mA, a Low might draw 100mA, but for exact figures, consult your user manual. The current flow number, may be printed on the fan hub label. Paul |
