Thread: NB and Mosfet cooling

    Default NB and Mosfet cooling

    Could someone recommend a NB and Mosfet cooler(air) for my EP45-UD3P please?

    The mosfets are located under the two other blue heat sinks, one set above and one set to the right of the CPU socket.

    The standard setup is more than enough cooling. You'd be better off spending the money on some beer and the time saved from fitting different heatsinks could be used to drink it .

    Unless you have really high ambient temperatures where you live, it's not worth doing, especially at only 445 FSB.

    If you are insistent on changing them, take a look on the thermalright web site, they have some nice north bridhe and mosfet coolers.

    ^Agreed. Reseating the coolers, removing the stupid bling covers that impede airflow, and installing a small fan over the NB cooler would be my recommendation.

    Good advice.

    My version of the UD3P has screw mounts for the northbridge and a push pin setup for the top mosfet sink.

    I've replaced the nasty thermal wax type stuff with a small amount of MX-2 spread nice and thinly over the P45 core. the mosfet sinks have a rather thick kind of silicone pad on them. I left these as they were, as likely removing them would have made the push pins nop longer able to hold the sinks with enough pressure onto the fets (because of reduced thickness if the silicone was removed).

    Be very gentle when removing and replacing the northbridge cooler, there's an exposed core under it with no other protection and it's potentially fragile.

    Also keep in mind that removing the heat-sink cap may void your warranty. If you do decide to do it, it is crimped on. The best way to remove it is with a pair of needle-nosed pliers. Gently bending the cap away from the body of the heat-sink at the shorter two ends (easier to get the pliers in, between the heat-sink fins)should allow it to come off. Using a screw driver could leave nasty looking tool marks. Be sure to pad the tips of the pliers to prevent them marking anything. It may be possible to replace the cap should you need to RMA the board.

    lol, nevermind, they'll stay seated.

    can you tell that I am getting bored.... now I am looking for projects... haah

    well, I guess that I will just settle down and use this thing I built for a while then... and drink a beer.
