    Default Will this be good enough to cool my north bridge?? UD3P

    Hello All,

    I have a Thermalright HR-05 SLI/IFX from a previous installed motherboard and I was looking to put in on my GA-EP45-UD3P.

    Thermalright states that it is compatible.

    Does our north bridge get hot enough that I would need a fan, or is the heatink passively cooled enough?

    Thanks for your help!

    I would imagine you would be fine without a fan, depends on your case airflow I guess. But yes, either way that should work nicely.

    Do keep in mind if you are remove the heatsink you should still put some heatsinks on your Mosfets as they will get very hot and blow if you do not.

    Enzotech makes some very nice Mosfet sinks, if you need some links let me know

    I drilled the nb heatsink (no "blue hats" on UD3 heatsinks)awhile back using the intel "manufacturers guidelines" to install a sensor with an external readout.
    I took the hs off the board first !.
    To cut a long story short ,i eventually mounted the sensor attached with a cable tie on the thickest part of the hs and shielded from direct airflow.
    Readout temps correspond v closely with the system temp readings.
    33-43C depending on load and room temp.

    Because my nb/memory fan is temperature controlled(sys2 fan header)
    sys temp goes for example 33-40 with steady 1 degree increases as load is applied.
    NB temp is more like 2 degrees higher at test start then at approx 36-37 sys temp,nb may be reading 35-36C after 30-60 min!
    2hrs+ on a warm day.
    Sys temp reads approx 40 and nb approx 43.

    I put this down to the fan speed..
    It goes from 900rpm approx at idle to 1300rpm max.
    Im asuming that the sys temp is "happy" at 40C whereas the nb would like a little more cooling under hi load.
    Yes i could have the nb fan funning full speed (2000 rpm) if i connected it to a different header but its just too noisy for 24/7.

    If using your cpu hs you could allways get an external reading sensor and attach it with a cable tie,Just make sure the thermocouple is in contact with the hs,
    The one im using is from an auto accessories shop (alpina brand).
    Overall tho, so ive read, the p45 doesnt get that hot unlike the 38 and some via chipsets.

    I am trying to figure out if I can remove the heatpipe from the MOFSET chips behing the CPU socket.

    I want to keep the MOFSET Heatsink, but replace the NB. I saw the ENZO MOFSET HS, but I wasn't sure if they would be big enough as compaired to the stock?

    Were these the ones you were referring to?


    Thanks,
    Jason

    Do you mean behind or beside the CPU as there is mosfets in both places?

    The ones above the CPU of course would be the easiest to do. The ones beside the CPU you may or may not be able to undue the Mosfet part of the heatpipe and the NB. If you do then you may or may not be able to angle the leftover part over the NB and still use the heatpipe.



    Mosfet is very small, I take it you have not looked or seen before eh? Yes, they are as small as those heatsinks and those are the ones I meant.

    Here is another mosfet on your board with nothing on it, so you can see the size of them >>>


    They also make a few full length ones but you would need to do specific measurements and maybe trim one down. I would suggest the mosfet specific ones or the larger double ones >>>
    Enzotech MOS-C1 Forged Copper Mosfet Heatsinks - Multi-Pack (10 pcs)

    These would also fit for two at once, but you would have to watch how you installed them so you did not short anything.

    Enzotech BMR-C1 Forged Copper BGA Ramsinks

    Enzotech MOS-C10 Forged Copper Multi-Pack (10 pcs)

    Thermalright also makes several variants of this type for mosfets, not sure which you could use though you would need to measure. Let me know if you want a site that offers more variants of these and I can link you >>

    I will be replacing bother the top and I/O mosfet. Thanks for the links, I will be getting the Enzo sinks. I'll post pics. :-)

    Lsdmeasap,

    I just purchased


    and I am going to be replacing both the MOSFET heatsinks.

    I purchased 2 packs (20), are there any other suggested chips that would benifit from these heatsinks?

    I won't need more than 20 will I???

    Thanks,
    J

    I have decided to install a fan on the NB heatsink. I will post some pics after I get it all installed this weekend.

    my concern now is the distance to the RAM modules and if the fan clips will hit the RAM. We shall see!!
