I have an AMD Phenom(tm) II X4 955 Processor running on an ASUS M4A78T-E motherboard. My processor fan was pretty loud, so I purchased a separate processor fan and heat sink, and plugged those in over my processor instead of the stock version. Well, it didn't work, and the processor got up to 130 deg F, and the computer shut down (that is my normal laptop temperature, but my desktop normally runs at about 110 deg). Also, the non-stock processor fan (Deep Cool is the brand name) only had a 3 pin plug for the fan, while the stock version had a 4 pin plug. So, I went back to the stock version, plugged it in, and it seems to run fine. However, now there is a problem. My cpu temperature is fine, still running between 105 and 110 deg F. My fan is still loud, but it runs ok. The problem is, now I can no longer tell what frequency my processor is running at. Before I ever swapped out the fans, my system load viewer would say what speed each of the 4 processors were running at. Now, it says they are always running at 2111.1 MHz. Also, when I boot up my desktop (box #1 below) as the services are being listed on the screen, I get this one line: Loading CPUFreq modules - hardware support not available skipped So here is where I need help. Are each of the 4 processors on my CPU really running at 3211MHz all the time, or is this just a false reading because the CPUFreq modules are not loaded? Also, is it possible that I damaged something on the motherboard or the processor when the temperature ran up to 130 deg for a couple of minutes, so that now the processor always runs at that speed? Is is possible that purchasing a new stock fan and plugging it in will solve the problem? Any other ideas would be greatly appreciated. -- G.O.

Changing heatsink/fans has no effect on clock speed. 130F is at the threshold of max temp. The processor was probably not damaged running at the temp for a short while, especially if the system is running OK now. Your cpu's clock is 3200 (unless you have a Blackie and have changed it). Less than that and differences between cores indicates that AMD Cool'N'Quiet - power throttingly - is enabled, otherwise all cores will run at the configured clock. If the kernel cannot load the cpufreq (power throttling) modules it usually means Cool'N'Quiet is disabled in BIOS or that the processor model cannot be correctly read. You don't say why the oem heatsink/fan "didn't work", but you may have done something that caused the board to revert to different BIOS settings. Make sure that the BIOS is seeing the processor model correctly and the Cool'N'Quiiet is enabled; the BIOS will also tell you the actual (max) clock. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That was it - I had unknowingly disabled Cool'N'Quiet at some point. I don't remember doing it, but I must have done it when I was messing around with making the BIOS do a fast boot, somewhat at the same time as when I had installed and tested the new fan. I have enabled it now in the BIOS, and I have my CPUFreq modules loaded and my system load viewer is showing variable speed again. Thanks for the help!! -- G.O.

Always be sure to use fans with ball bearings and not any using sleeve bearings. The words "ball bearing" should be somewhere on the fan. Personally, I'd use a more expensive brand known for good quality such as U.S. Toyo Fan rather than some doubtful no-name Chinese brand. Although the price is a bit higher, it is still much less than a new CPU, mobo, power supply, etc., and these fans last almost forever. Sleeve bearing fans have a short, unstable life and tend to be very noisy until they fail. They should never be used in critical applications such as CPU, power supply and component cooling. jd -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Thanks for the tip. Do you know if stock fan that usually comes with an AMD processor a sleeve bearing fan? The only thing I have to compare it with is that it really cools off the processor so much better than the Deep Cool brand that I bought (which I think is more than just a no-name brand, but is less than the stock brand). -- G.O.

The stock hs/fan changes with socket and/or platform. At 110F you are comfortably within the operating range. The stock fan usually lasts several years at minimum. It also is certainly not quiet. You didn't say how the Deep Cool "didn't work", other than overheating. Unless the fan was outright defective, it is much more likely that the cause was how the heatsink was mounted. You might want to take another look at that. Unless you are overclocking, you should be fine with the stock heat sink; just replace the fan. Overclockers and performance modders are partial to Delta, Scythe, and Noctua. Antec, Rosewill, and Apevia make decent budget fans. By the way, the 4th pin is for fan speed regulation. Your Asus board probably has the "Q-Fan" feature which adjusts fan speed relative to cpu temp, i.e., when Cool'N'Quiet down throttles the cpu the temp will drop and with it the fan speed and noise. Hope that helps a bit. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The fans that come with AMD CPU kits are good and they should still have ball bearings. They probably would not if the fans are swapped out by the resellers or if the resellers buy bare CPU's bulk and adds fans themeselves or if the CPU's are repackaged used ones or returns. (Fry's has been notorious in the past for reselling used returns as new with missing or wrong parts.) AMD fans used to have tamper evident holographic labels with serial numbers. Hope this is still the case. I haven't bought any recently so I can't say if they still do. Perhaps someone else knows what the current state is? Generally, the larger the heatsink and fan the better it will cool. Other factors affecting cooling include the kind of thermal compound and how it is applied, ambient air temperature, air flow, humidity, whether there is fresh air flow or not, the size and position of obstructions to air flow and how dirty the air is. It can get a little complicated. All fans make some noise. How much and what kind depend on the design and the speed. But sleeve bearing fans make squealing or rattling noises, obviously mechanical noises while running. They may be quiet in the beginning but eventually, unless they seize first, they will start squealing, et cetera. And then if they suddenly are silent, they have likely seized and stopped turning. If you've bought cheap, Chinese-made small room or personal fans from a box store you've likely heard them start making loud noises or have seen them stop turning after a few weeks or months of use. These fans don't have ball bearings and when they fail they make sounds similar to the smaller fans used for PC's. Sorry for the long-winded response. I hope it's not too much information for anyone. There used to be a hacker's article somewhere about problems with using sleeve bearing fans in computers that covered this very extensively. If I could find it I'd post it's link. jd -- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
