    Processor heatsink fell off...

    It's an NVIDIA Zalman heatsink+fan assembly.

    It came mounted on the motherboard I got from my brother.

    It looks like the metal clips just broke. I've looked it up and it has happened to a few other people before me too. The heatsink is really heavy and rests on just some small metal clips.

    Luckily I didn't power it on, I noticed before...

    So... is it fixable? I have a heatsink+fan assy from a broken Gigabyte motherboard, but I'm not sure if it will fix.

    Re: Processor heatsink fell off...

    Why don't you just try another heatsink? Salvage a x-clamp from another mobo...
    P.S. I would kill for a sweet PNY 8800 like that one Is it single slot?

      It's 9800 GT actually . Single PCI-E x16... another freebie from the brother who gives me all his old (~2-3 years) computer hardware.

      I will see what I can do about using the Gigabyte heatsink. I don't think a particularly powerful heatsink is needed to keep an AMD Athlon FX64 cool.

        That can't be 939 it's an AM2 or 754 system... Just get a newer retention bracket that's made out of better plastic...

          Abit KN9 Ultra motherboard, does that help? Processor has AMD Athlon FX64 engraved on it. It's dual core 2.8 GHz and will overclock to 2.9GHz before crashing... I know very little about computers (I just know it's a very fast processor for me), engineering is more my thing... The motherboard is full of Rubycons.

            Hmm, looking at this heatsink+fan as a replacement (is it a stock heatsink/fan?) I am using the processor to rated specifications (2.8 GHz, default BIOS...), as noise is not a concern (it has 6 fans + CPU fan!)

            http://www.ebay.co.uk/itm/New-AMD-CP...item46014e3322

            The metal clip is completely broken, I don't think I can use that old Zalman thing, but it seems like overkill anyway.

              Yes that looks like a stock AMD cooler. Will do the job but keep it clean.

                  The metal part for clamping the heatsink to the processor is what broke. Sheared right in half. The motherboard is okay...

                    I would check the DRAM clock and maybe lower it to get past 2.9.

                    You should be able to get at least a + 200 Mhz OC.

                    Failing with a + 200 Mhz OC, which is tiny for today's standards, reminds me of my T-Bird 900, where it will crash at 1050, with "STOP:0x0000000A IRQL_NOT_LESS_OR_EQUAL"

                      Heh, I have no need to overclock it. It is already extremely fast for me and should suit me for years to come. I have a similar processor in my media PC, but it is the single core variant (friend's old PC.) It is underclocked to 2 GHz to keep fan speed low and temperature low, and it still performs extremely well... I was able to drop the clock to around 1 GHz before it couldn't play 1080p...

                        I think that would be an Athlon 64 FX-62, not FX64. Double check. If yes, those are rated for 125W TDP - so no, that heat sink is not overkill at all.

                        Doesn't sound like something that zip ties or thick steel wire won't fix . I've done it with many other heat sinks. Works better than the original most of the time.

                          Yep... you're correct. Would I really use 125W with both cores maxed?

                          I wish I could, but there aren't many holes around the motherboard which would support such an arrangement.

                            I wouldn't use that fleabay stock heat sink with a 125W CPU. I'd go with a coolermaster hyper TX3. They are cheap, but surprisingly quiet and effective.

                              I found someone selling it for £4, so I'm going to give it a shot. In the worst case I will wait before I start using this PC to play games. I just finished Crysis for the third time before the heatsink fell off. I will see how well it performs. If it gets too hot, I will upgrade it. The media PC (with single core variant) uses a stock cooler and it runs at less than 40°C most times.

                              I really, really wished that manufacturers of processor heatsinks would specify a thermal resistance of their heatsink. However, this would allow proper comparison and then it would no longer be based on looks! A good processor heatsink (IMO) would have a thermal resistance of below 0.3°C/W C-A (case to ambient, with 90% rated speed fan cooling.) Add in thermal paste of 0.1°C/W and this allows 125W dissipation at 40°C ambient, reaching a maximum die temperature of 90°C.

                                Yes, maybe even a bit over. TDP is like a high-average for what your processor will use. At idle, it will be well below the TDP and at 100% load, it can peak above it.

                                  Okay, so the heatsink/fan assembly arrived today. It looks like it has a thermal interface material fitted to it already. I do have thermal paste if I need it, but do I need it if it's got this already?

                                    strip that away you need fresh stuff always.

                                    So I will avoid that brand heat sink lol.

                                      That's the typical thermal adhesive that ships with all AMD stock heatsinks. It's pretty good (and also a PITA to remove). Snap it on and that's all, no paste needed.

                                        Wouldn't he need to move the gell on his processor before applying the fan with the thermal adhesive

                                          Problem

                                          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                                          Seeking Advice on Enhancing Heatsink for Main Processor on SAMSUNG TV Motherboard
                                          by Ven
                                          Hello everyone,

                                          I'm looking to upgrade the heatsink on the main processor of my TV's motherboard for better cooling performance.

                                          The current heatsink is a square-shaped one (2.8cm x 2.8cn) with a basic design, and I believe a more efficient heatsink could help with thermal management and potentially extend the life of the TV.

                                          I'd appreciate any advice on the best type of heatsink to use, specific product recommendations, and tips for installation.

                                          If you've done a similar upgrade, I'd love to hear about your experience and any challenges you...

                                          Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                                          i have a asus N43SM i7 2th gen and i have a big probelm

                                          After hitting the metal part of the touchpad or the sides of the mouse is metal, the system locks and the image crashes !

                                          Sometimes, when I didn't work with the notebook for a few minutes, after I touch the touchpad, the image confused​ and the system locks ( See Down Picture). I have to turn the system...

                                          I was working on this machine yesterday and I now going to use an incandescent lights instead of a fuses to figure out what the issue is with it blowing control voltage rail but this not the only issue the coolant pump failed the meager test as well as the main motor as well this motor has 12 motor wire leads instead of the normal 9 wires

                                          This metal lathe has a weird motor setup it has a soft start motor with a “Y” and a delta type of motor winding setup and it is not done in the motor pucker head enclosure it is with four different contactors wired in a configuration I have not...
