Newcastle running hot

    Hiya,

    I need some help with keeping my PC cool. Currently, I have a Swiftech MCX 6400-V heatsink with an Arctic Cooling Fan 3 TC on it. Now idle temps are not that bad, I'm idling at 38 C. However, load temps are terrible - I have about 58 C full load (which is always, as I have D2OL as a service, and that uses my CPU to 100%, therefore my temperature is about 58 as soon as I boot into Windows). I am running a Newcastle CPU.

    Firstly, the fan has thermal control, so I thought of moving the sensor onto the CPU block (defaultly it comes with the sensor above the fan). If I wanted to completely cancel out thermal control, could I just put a piece of wire between the two contacts on the thermistor (and thereby get low resistance)?

    Secondly, I have about $35 to spend. So I have several options:
    A)Get a window for my Stacker, get a few blowholes cut, and get some AS5 (currently I have some no name paste)
    B)Get a crossflow fan for my Stacker and AS5.
    C)Get a Arctic Cooling Freezer 64 Pro and AS5.(TT BT is too expensive)

    Any advice welcome.

    but have you enough thermal paste and a good strong contact and are you sure that is the right temperature because some mobo`s can give dodgey readings :/
    i would get the thermaltake sonicTower and stick a 120mm fan on it they are really good or the good old xp90 :D

    I'll have to check the HS one more time, though everything should be OK, I used the original AMD backplate, that is the only reason of which I can think that would give me bad contact. Other than that, which option of the above would you reccomend I get (A, B or C?)?

    well if any go for tha artic frezzer and just make sure you have good air flow though the entire case

    D) Get an XP-90 and a cheap high-rpm fan

    Well, I just found out that I can maybe get a Thermalright SI-120 + 120mm 120CFM fan or an Akasa AK920 Evo 120 - Amber Edition (both the same price), or a Thermalright XP-90C (also the same price). What would be the best combo?

    You are way off the right path to the solution to your problem! The heatsink is just FINE, really. The Fan is the one holding its performance back. That ArcticCooling Fan is a case fan, and to use a "TC" model for CPU cooling purposes is just plain folly!
    Even (EVEN!) the AC models that are HS+fan with "TC" out of the box are, forgive my strong opionion, CRAP. I had very high temperatures on a AC HSF with "TC" and mailed AC about it, whether that was indicating a product error, maybe a sensor dislocation or whatever. They wrote back that the temps of >70°C under full load (oc'ed AthlonXP 1400+@2400+) I had are just fine, the core can take 90°C. Wow. Now that's what I call arctic temps.

    Get a decent Papst fan, they are (pick an according model) silent and very good at being undervolted to be even more silent. My advice: Pick a "strong" model and buy a 12V->5V or 12V->7V adapter or even better a Zalman potentiometer, whatsitcalled, google :) .

    If you still want to buy a new HSF for whatever reason, the AC Freezer64 is great. I have nothing against AC at all, its just the "TC" models that are just crap.

    I'll have a look into the fans. I had a 120mm fan on it (through adapter), and the temps weren't much better.

    Well according to that test the Swiftech is quite OK:
    http://www.systemcooling.com/swiftech_6400v-04.html

    To give you a value for comparison: My oc'ed Newcastle 2800+ has temps under full load of 53°C, but that's with 1.6V VCore and in a heated room. Case temperature is 30°C. The HSF used is a Thermaltake Venus 12 with the fan at 2200rpm (almost lowest rpm value I am able to select, but no louder than lowest setting). I prefer silence over lowest possible temps.

    Edit: I'm a numbercruncher too, SETI@home runs all the time!

    Hiya,

    I solved it by getting a high power 80mm fan and a duct... my load temps are 45 C load (approximately 12 C drop) and somewhere in the low 30 at idle.

    EDIT: I also have a cross flow fan on the way, which should drop temps by another one or two degrees hopefully.

    when i had my 3400 newcastle what i did is ordered a 60mm fan which spins at 8000rpm and that was preaty noisey but did the job till i got my gigabyte 3d ultra cooler but your 2800 shouldnt be runing so hot unless you are sticking stupid voltages though it
