    Quiet 1U Socket 370 heatsinks

    Anyone know of a heatsink/fan that's relatively quiet, usable in 1U enclosures, for Socket 370?
    Was thinking about replacing a fan; while it still works and probably will work forever, it's extremely noisy as the fan rubs against the fan cage with a worn out bearing...

    The fan is weird, it's a squirrelcage type fan sucking air from the heatsink and expelling it to the side unlike the typical suck down and into the heatsink.

    CPU is a Celeron Tualatin... so 40W or so.

      Quiet? 1U? Is that possible?

        it is possible, but not usual or easy.
        you need a big flat heatsink like the flower ones,
        and a fucking big fan that runs slow.

        but the other problem is the case, you need to suck the air out or you just create a vortex of hot air going around and around.

        it depends on the amound of space in the rack.
        the other thing is rack psu's are often loud because they are small and output a lot of current.

            Yeah it's just a usual 1U- high rackmount, but I don't have a rack and this is in my house, not a datacenter

            The small 1U case has a few small 1.5" fans on it to suck the hot air out. I'm sure that's also making significant noise, but the current cpu fan with its scraping is making much, much more...

            I do wonder if I can trim a bit off the blades so that it will stop scraping against fan encapsulation...

            The current fan is like a turbocharger, if you think of it like that. The blades are totally encapsulated, it can never eat fingers. This thing blows to the back where the case fans are, and sucks up from the heatsink (think of a car turbocharger and put that on top of the heatsink, inlet pointing straight down to heatsink, and turbine is an electric motor on top)...

            I'm open to replacing both the fan and the heatsink. Was hoping the virtue that it's a Celeron Tualatin that perhaps I can get away with a smaller fan/heatsink but probably not...

              Colocation? $50/mo 1U 1A Just a PM away!

              But seriously, this seems to be your only option I can find in stock at Amazon. It won't be quiet but should be an improvement?

                I'm sure this firewall box will do great at a colo!

                Hmm... that might just fit... And anything is quieter than a fan that rubs its blades on the housing.

                I just wonder how it will perform with airflow dynamics would need to change...

                  You could sit in front of it and blow on it when it starts beeping for overheat?
                  /sarcasm

                  Doesn't it have some fans blowing back throughout the case or no?

                    Re: Quiet 1U Socket 370 heatsinks

                    Yes it has case fans too, but the original turbofan 'exhaust' was pointing towards the case fans - with a downwards spreading airflow fan, the air movement is completely different now...

                    I don't think this thing even has thermal sensors in it. Would have to use an external remote thermometer to see if it will overheat or not...

                      woah...found a source for the same heatsink/fan....

                      http://www.antarespro.com/6507757-item-COOLJAG-9BC.aspx

                      It indeed is a dual ball bearing. Except the spindle broke, that's what happened to this fan. I think I'm going to see if I can epoxy the spindle back onto the rotor...

                        It's called a radial or centrifugal fan, it's absolutely the best option in a 1U case, because there is no room to pull air in from the top like on a conventional fan.

                          I have peltir element glued to heatsink with something thick and sticky like putty... it cant be separate with force or heat without risk of breaking ceramic or damaged semiconductor layers due to force (eg if try twisted, pulled, lifted)... method that I am using is a single thread for needle (thin and firm thread of pure polyester that cant break with bare hands without glowes), and using it like a saw between heatsink and peltir. I holding a heatsink with knee against table. It slowly cut throug putty and release glued parts. It is slow proces, but preserve undamaged component and heatsink....

                          Possible to convert eMMC Socket to a micro SD Card socket?
                          by Isabella91
                          I have seen many posts where the eMMC can be read via a SD card reader, however can the opposite be achieved?

                          Read/Write a Micro SD Card from an eMMC Socket.

                          I have a Motherboard with a Kingston BGA153 ball socket, using HS400 bus mode, which is 8bit, as Micro SD is usually 1bit or 4bit mode, I accept that a loss of speed in read/write will occur, but I would sill like to convert.

                          Theoretically speaking, Im thinking if I hard solder DAT0-3 from eMMC to SD Card Reader, this should force 4-bit mode, or only DAT0 to force 1-bit mode.

                          Samsung R530 Bremen motherboard cooling
                          by Ace Perception
                          Hi,
                          I'm wondering if anybody out there has much knowledge of Samsung Bremen motherboards.
                          I've got a Samsung R530 which is about 10 years old, over the last 12 months it developed a worsening problem where when asked to do much work it would shut itself down. I had a good idea this was due to overheating which was confirmed by a temperature monitor programme which showed little balls of fire next to the various internal temperature readings. I could also prevent it shutting down if I placed a huge fan running at full speed in front of its air intake!
                          So I went in pursuit of...

                          Acer AN515-57-577G JDIMM1 socket not working.

                          Hello, Acer AN515-57-577G JDIMM1 socket does not work. GH51G LA-L181P, 2x DDR4 RAM, both good, both work well in JDIMM2, neither works in JDIMM1. The laptop displays BIOS, when the JDIMM2 socket is occupied, you can run Linux on USB, then everything seems to work ok, there is internet access and you can browse the contents of the 512 GB SSD in Windows, but starting Windows ends with an eternal spinning circle, maybe there are corrupted files. When the RAM is inserted into the JDIMM1 socket, the laptop starts but there is no image and the downloaded current does not change and the output is ~2.25A....

                          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...
