    heatsink recommendation

    I have an AN35N-Ultra mb and am thinking of changing to a different heatsink when I install a mobile 2400+ that's on order. I am interested in the Thermalright ALX-800, but am concerned that it will not fit properly on this mb. Anyone know if it fits or can anyone suggest a comparably priced heatsink (~$30 for hs plus fan) for this mb? I plan to overclock this cpu, but not to the limit (2.4 GHz if I can).

    the alx is a good cooler and should fit ok maybe Szandor will see this message and respond to it.I think he is using this heatsink.
    asfar as getting 2.4ghz out of that 2400+ good luck maybe on water cooling and all of the newer 2400+ are multiplier locked.
    i have the 2400+ also and have reached speeds in excess of 2.3ghz but @11.5x200 400mhz fsb and 1.825 volts mine was easily unlocked with the nforce2 board but the newer ones are really locked and you may need to do the wire trick to unlock it

    Fitz, he said a MOBILE 2400 which will NEVER be multiplier locked. As for hitting 2400, that's quite likely (I've had no problems doing so on air with mine).

    The ALX-800 is a good heatsink, but not a great choice for overclocking and probably won't get you to 2400MHz. It should fit although you might need to mod it a little.

    ALX-800 is a decent HSF, make sure to use an 80mm fan, preferably with a speed controller so you can run quiet when surfing and crank it up for benching and gaming.

    I use the TT Volcano 12 Extreme, still $30.00 delivered from AJump last I knew, this comes with 2 speed controllers, a big honking shrouded copper sink with 66 micro-fins and an adjustable 3 bladed 80MM fan, its good versatile cooling and bang-for-the buck.

    If you have more money, check out the Thermalright SLK line.

    As your chip is a Mobile which runs at a lower default VCore I think with a good fan you should get 2.4Ghz using the ALX-800. They seem to need about 1.7-1.75V to run these speeds from what I've been seeing so it should provide sufficient cooling to do that as long as you have adequate case ventilation IMHO. I would still consider the V-12 for the extra few $ as it will definitely carry you further than the ALX-800 will.

    Good Luck!

    The ALX-800 *will* fit. I've also used an SLK-900A on the AN35N Ultra.

    Yeah I know for a fact that the ALX-800 will fit as stated already but I 2nd Szandor's recommendation for the Volcano 12 Extreme! I have this HSF on my AN35N setup it it works great, it is not a quiet HSF by any means unless run at low speed but boy at the 5000+ rpm high it keeps the CPU very cool!

    btw just join the site and the system in my sig is new, let it burn in at stock for a while, thats why it is only at 11x175fsb. I am taking it up in steps running memtest and benchmarks at each setting. I am guessing I will have to loosen my mem timings eventually to get 200+ fsb but I am going to see how far I get.

    Welcome to the Forums PhoenixBlade!

    Try flipping the fan on your V-12 over so that it draws air through the sink rather than forcing all those CFM through it which creates turbulence which equals noise. By reversing mine I cut the noise down considerably and knocked 2c more out of my temps as the air flow is smoother and thus can transmit more heat away from the fins, @2200RPM it is near silent.

    Very good method for OCing, take your time and make notes. Too many try to jump up too quickly and experience problems, in addition you can track your the performance of your rig and can compare the settings to the performance, timings and temps.

    I use Sandra Arithmetic, Multi-media, Memory Bandwidth tests & a loop of 3DMark to track my progress with notes on VCore and VDimm settings and all timings. I run 2 loops of Memtest and 1/2hr of Prime, if all tests OK I go to the next highest setting and repeat the process. It does take longer but in the end you'll have a very good picture as to your rigs capabilities.

    When you find a particular setting that you want to run for awhile I run 8hrs of Memtest, usually overnight & 12-24hrs of Prime before I condsider that I'm "stable".

    Good Luck!
