Motherboard Replacement / Compatibility

Solved

Hello, I would like to change my motherboard because the one I currently have is dead. I found another one, but I don't know if it can replace my old motherboard. It is compatible with my i5 processor, but the dimensions are not the same, so I'm not sure if that is a problem or not.

Here is my old motherboard: https://support.hp.com/fr-fr/product/hp-pavilion-500-400-desktop-pc-series/7161732/model/7547733/document/c03916434

Here is the new one I want to buy: https://www.cdiscount.com/informatique/cartes-meres/msi-h81m-p33/f-10765-h81mp33.html?idOffre=-1
The dimensions are not the same as my old motherboard; does this pose a problem?

(Just in case, here is the second motherboard I want to buy: https://www.cdiscount.com/informatique/cartes-meres/asus-h81m-k/f-10765-asu4716659595823.html?idOffre=137007270#desc)

My graphics card: AMD RADEON HD
Processor: Intel Core i5

Thank you ;)

    Hi,

    "Up" for?

    You ordered another motherboard... what more do you want?

    It's the same platform, so the processor will be compatible.

    You won't be able to make "more holes" because the holes are specifically placed for the format and you don't drill a motherboard like you want, nor a case...

    That said, a format is a format, if the standard is respected, a Micro ATX motherboard will be compatible with another Micro ATX.

    The dimensions may vary, depending on what connectors the motherboard has, etc.

    Good evening,

    Alright, thank you very much, so even if the dimensions are different, I will still be able to install my new motherboard, that reassures me, thank you for responding!
    Have a good evening.

      As long as the format is respected, yes.

      A format is standardized and the dimensions are also standardized in principle, even if they are often "approximate" as long as the holes line up correctly, and that is determined by the format.

      Okay very well, I will receive my motherboard in 1 or 2 days, I will leave a message here to say if it's good or not, your message reassured me a lot, thank you! :)

    Hi

    You're likely to be disappointed when you see that you can't connect the front panel ;-)

      The front panel, if it's the power supply coming from the power button cables of the computer, I managed to connect it, even though it's different from the others; usually, this cable is in several pieces, but on my computer, it's all in one.

    Hello,

    I received my motherboard, I was able to connect ALL the cables, except for one, I believe it's the one for the front USB ports, it has 2x10 pins, I can't connect it, but it's not necessary for the computer to function, I was able to turn on the computer, etc... I didn't even need to reinstall Windows, but my only problem is that the fan on my processor isn't running, so I quickly turned off my computer when I noticed it, but my processor managed to reach almost 100 degrees. When I connect the processor fan to SYSFAN, it works, so it's not the fan, I think it's due to a defective motherboard, so I'm returning the motherboard and they will send me a new one, hoping it works.

    And for the 2x10 pin cable that I can't connect because there is no such connector on the new motherboard, I have several options, either change the cable or use an adapter, that's what I think I will do.

      You were lucky with your case; often it's a block specifically made for the motherboard inside.

      And you can connect two USB ports on the front without any issues, right next to the SATA ports ;-)

      Be careful with the keying, one might be AUDIO.

      Negative for the 2x10 pin connectors (the famous connectors usually "blue" intended for USB 3.0), this implies that the motherboard has them... However, the one mentioned above does not have them... :-)

      By 2x 10 pins, I mean this one:


      Moreover, it's hard to confuse with audio, given the format... ;-)

      I still had some trouble screwing in my new motherboard because I had to apply quite a bit of force to align it with the holes for the screws and then put in the screw. By the way, this motherboard only requires 5 screws (or 6), while my old one needed 8 screws!

      My front USB ports (there's SS written on them) are impossible to connect because the cable has a blue connector, and it needs to be plugged into 2 * 10 pins, but on the MSI motherboard, there isn't a slot where I could plug in 2 * 10 pins, unless I connect the 2 * 10 pins to a USB slot with 2 * 7 pins, but I don't think that will work?

      No, you shouldn't

      In this photo; http://article.tech-labs.ru/img/article/31954/Gigabyte_A75M_S2V_general_view_6.JPG
      You have both standards, you can clearly see that it won't fit.
      You need to use an adapter:
      http://www.ebay.fr/itm/Generique-Adaptateur-interne-USB-3-0-vers-USB-2-0-N-A-Noir-NEUF-/332273708572?hash=item4d5d0e6e1c

      because I had to force quite hard to align it with the holes to screw it in and then put the screw,

      Uh....that's concerning, normally it's standardized and you shouldn't have to force much for it to fit, did you have all the pins lined up with the holes? None should be in direct contact with the motherboard?

      Or if you really want to take advantage of the front USB 3.0... just install an internal PCIe USB 3 card like this one: https://www.ldlc.com/fiche/PB00153074.html

      Of course, you still need to have a free port for that... :-)

    Hi

    on the HP case, do you have a 3.5" slot to install >>> an internal memory card reader <<< that has a USB 2.0 port

    see you

      on your case, you don't have a 3.5" slot with a front opening

      when you open the front, you have nothing = http://h10032.www1.hp.com/ctg/Manual/c05031520

    Hello,

    I just changed my motherboard today, everything is working well, all the fans are spinning, but I have now 2 questions:

    Is it normal that now that I have changed the motherboard, the fan on my processor is much louder?
    Do I need to reapply thermal paste or not?

    Is it bad if the fans are running fast? Is it bad for their lifespan? When I launch a resource-demanding game, the fan on my processor runs very fast, around 80%, and consequently, the temperature of my CPU is stable at around 70 degrees.

    Are the settings for my CPU fan properly configured?

    Thanks to everyone

      Should I apply thermal paste again or not?

      Please reassure me, you did clean off the old one and applied the new one, right?

      No, I didn't change the thermal paste; I kept the old one, but the PC runs well, it doesn't overheat, yet my fans are quite loud anyway :/ Even though they're not spinning fast at all :/

      The thermal paste is always changed when the heatsink is removed.

      As for the fans, you need to check if they are 3 or 4 pins. If they are 4 pins, they can be regulated via PWM. Otherwise, the fact that they are running fast may be due to them being 3 pins and the regulation not working as expected...

      Alright, I will change my thermal paste as soon as possible

      The CPU fan is indeed a 4-pin, and the external fan is connected to a 4-pin SYS FAN, but the fan only has 3 pins, yet it still works on the 4-pin SYS FAN

      Thanks again! :)

      Yes, so the case fan won't regulate itself, makes sense for a 3-pin.

      But the fact that you haven't changed the thermal paste, in my opinion, is precisely why it's overheating and the fan has to run at full speed to cool it down.
