Need a decent cooler for a stock Athlon 64 3500.
I have an Athlon 64 3500 that runs a little warmer that I would like
it to with the stock cooler. The maximum temp range for this model is listed as 45 to 65 on the AMD website. http://products.amd.com/en-us/Deskto...il.aspx?id=103 My CPU temp used to be in the 40s at idle, but now, after a recent BIOs update, idle temp is around 50 to 60. I ran a stress test with Prime95 for about 4 hours last night, and the CPU temp was topping out at about 70. So, I would like go ahead and get a new CPU cooler. As I was looking at the Zalman website, I noticed that there were disclaimers that 939s should have coolers that weight more that 350 grams. Is that really a limit that I should strictly adhere to? The only 350g Zalman was the CNPS8000, but I read a review that claimed that the 2-part mounting bracket was crappy and caused great difficulty when trying to get the cooler to mount flush with the CPU. So, I don't think I want to fool with that one. So, what's a decent cooler that you would recommend for a socket 939 that could be had for about $30? Oh, by the way, my motherboard is an MSI, MS-7093 . http://h10025.www1.hp.com/ewfrf/wc/d...483902&lang=en |

I've got one on a San Diego 4000+ at 2.8Ghz. $20. It cools better than the monster Zalman unit I have the same unit, and I thought the Zalman was good. |

You mean this one? http://www.lhdigital.co.uk/product_i...cts _id=93058 It weights 528 grams. So that brings me back to the question of weight restrictions. How much is too much for a socket 939? If I install a 500g cooler, am I going to have to start carefully handling to PC like it's a vial of nitroglycerin? lol BOOM! The contents of my wallet get blown to smithereens! |

Zalman makes Socket 939 coolers that are over 2 Lbs (the S7700 Cu on my Opteron 185 / A8N-E for example). There's zero problem with the weight of the cooler installed and running. It's a shipping or moving the installed CPU cooler when installed on the mainboard when it's a potential issue. It can be gently carried from one room or place. But if you ship it, bang it, drive it around or other g-force generating activity, these large mass of the cooler/fan can damage the PCB and related CPU brackets and socket. This is copied from the Zalman site: "The maximum weight for a cooler is specified as 450g for Intel Socket 775/478 and AMD Socket 754/939/940. Special care should be taken when moving a computer equipped with a cooler which exceeds the relevant weight limit. Zalman is not responsible for any damage that occurs when moving a computer." Clearly, the warning refers to possible PCB, retaining bracket and related damage that MAY occur when MOVING a computer. Why would Zalman market and sell 600-900 gram coolers specifically designed for these and other units? |

I guess more recent motherboards with newer sockets for faster, hotter processors are built to better handle a higher-weight cooler. |

Need a decent cooler for a stock Athlon 64 3500.
OK, now I have a new problem. The BIOs on my motherboard are extremely
limited and do not allow me to disable to RPM monitoring of the CPU fan. I think this will result in my BIOs preventing my computer from starting in I install the fan that comes with the AC Freezer 64 Pro. That's too bad, since I was reading a lot of positive reviews, and I was looking forward to using it. So, in light of this limitation, what cooler would you recommend? I just used SpeedFan to push my CPU fan to 100%, and the RPMs topped out at about 5600. So, I guess I need something that can do at least that. |

Your presumption that the BIOS will prevent the PWM version of the ACF 64 Pro from running is wrong. You simply have a non-PWM m/b. Buy the non-PWM version. The PWM version will work too, just runs at full speed. |

I just used SpeedFan to push my CPU fan to 100%, and the RPMs topped out at about 5600. So, I guess I need something that can do at least that. Do you have details, as to what RPM range the motherboard doesn't like ? The manual I could find here, for MS-7093, doesn't go into details for the hardware monitoring. (Apparently, there is more than one motherboard with that number, and I downloaded this, just to see how bad the BIOS screens are.) http://download2.msi.com.tw/files/do.../E7093v1.6.zip It almost looks like the CPU fan header is a 3 pin. The AC Freezer 64 Pro uses a four pin connector (according to the description on Newegg). Which is not a problem. --------- (Keying tab) Four pin header X X X X PWM RPM +12 GND --------- (Keying tab) Three pin header X X X RPM +12 GND If you plug a four pin fan into a three pin header, the PWM pin won't have an electrical connection. A floating PWM allows the fan to run at full speed, so should not interfere with normal operation. In principle, a four pin fan should not be fed a variable voltage on the 12V pin. So you'd want to keep the fan running at 100%, so that the motherboard feeds 12V to it. (The reason for this, is the PWM uses a transistor inside the fan hub, and to help keep the transistor saturated, it helps if the fan is being fed full voltage. The condition they're trying to avoid, is having the transistor partially conducting, which increases the internal heat in the transistor.) The first review on Newegg right now, mentions that the AC Freezer 64 Pro ran at two speeds for the reviewer. It ran at "450 RPM" and "2400 RPM". Maybe this had something to do with motherboard fan speed control, but the comment is a bit strange. http://www.newegg.com/Product/Produc...82E16835185125 If I was expecting trouble, I'd probably buy and keep handy, a fan power adapter. What this thing does, it draw the 12V from the Molex disk drive connector. (You may need to purchase a Y cable as well, to get enough connectors to plug this in.) There are two fan connectors on this. The middle one goes to the three pin on the motherboard, and delivers the RPM signal (to keep the BIOS happy). The right hand one, goes to the fan. The purpose of using this, is so that the motherboard fan control, cannot drop the fan speed (and the 12V level). And the fan will run as close to 100%, as it is capable of. That gives you 2400 RPM, and one would hope, enough to pass the RPM minimum of the motherboard. (I have one motherboard, where 1800 RPM is the minimum. Modern motherboards are a bit more intelligently designed, and have a lower minimum than that.) "Rosewill RCW-311 12 inch Fan Power Supply Cable - Retail" http://www.newegg.com/Product/Produc...82E16812119149 "APEVIA 1 x 4Pin To 2 x 4Pin Cable" - Y cable for disk drive power http://www.newegg.com/Product/Produc...82E16812201006 The minimum RPM that the hardware monitor provides, is determined by the "scaler register". It sets the time base for the speed measurement. Some motherboards don't crank this to accept low fan speeds. My motherboard has a couple notches left, which would allow it to sense a slower fan, if the BIOS had been set up that way. Speedfan is pretty clever, in how it uses the scaler register. Speedfan "autoranges", changing the scaler register until the bits collected in the measurement register occupy a significant part of the dynamic range of the register. Other programs are not as clever. MBM5, the Motherboard Monitor program, doesn't change the scaler, but works with the value already set. And what that means, is if used by itself, MBM5 might read zero for a fan. Then, when Speedfan is used, it will get the reading. Then, if you used MBM5 again, suddenly it would be working (because Speedfan adjusted the register). Of course, none of what happens in Windows, helps with the BIOS check of fan speed during POST. The above is just to point out some of the things that can happen with Windows programs, versus the hardware monitor chip. If you wanted to use the AC Freezer 64 Pro, having an adapter cable handy, may give you an option to help it run full speed. If it turns out to handle the lower fan speed without a problem, then perhaps the adapter cable would not be needed. There is yet another alternative. You can take a separate fan, and plug it into the CPU fan header, to keep the BIOS happy. You would then need a means to power the real CPU fan, as the header would be occupied by an RPM equipped fan, whose purpose was just to keep the BIOS happy. (Examples of some small fans that spin fast. The whine from one of these would drive you bananas. The fastest one here does 8000RPM. I have an older model of their 40mm fan. ) http://www.actrx.com.tw/datasheet/20...0_I_12-24v.pdf Paul |

Your presumption that the BIOS will prevent the PWM version of the ACF 64
Pro from running is wrong. You simply have a non-PWM m/b. Buy the non-PWM version. The PWM version will work too, just runs at full speed. The reason that I assumed that it wouldn't run is due to the impression that I got from the AC website. They seemed to imply that the only way to resolve the problem was to modify the BIOs settings. From their site: "The Computer switches off after a couple of seconds The BIOS of some mainboard manufacturers compares the speed of the fan with a specified value. If the fan speed does not match the specified value, either the PC emits a warning or switches off. Contrary to the temperature control, the RPM control is of no importance, since fan speeds will be between 500 and 7000 RPM depending o*n the type of fan. This RPM control can de deactivated in the BIOS settings. Please consult your mainboard manufacturer for more information regarding these settings. In the case of the PC is not booting or immediately switching off, attach the plug of the cooler to the auxiliary power of the mainboard and attach a second fan with higher RPM to the primary power socket. Now the PC can boot allowing the RPM control to be deactivated in the BIOS settings. We recommend using a temperature control instead of a RPM control. The cooler does not need to be removed from the processor for this procedure." http://www.arctic-cooling.com/cpu2.p...0&data=6&disc= Also, Wikipedia has a comment on the differring behaviors of various PMW fans. "The behaviour of a PWM fan plugged into a 3-pin header (i.e. PWM signal disconnected) varies depending on model. Intel CPU coolers run at their fastest speed, as a failsafe (but can be slowed by connecting pins 4-1); others may run at the lowest speed (but can be operated at the fastest speed by joining pins 4-2)" http://en.wikipedia.org/wiki/Compute...pin_assignment Of course, that also answers my question by giving me a way to "set" any PMW fan to full speed. I haven't had any experience with PMW fans before, so this is something else that I am "just learning about". I thought that the "rated speed" was the only speed that a fan would actually operate at. |
