    well I'll see what happends. anyway - I'l definitely bench both 4870's 'if' i ever get it back.

    But i thought 3d06 didnt support duel or crossfired cards??

    yea 06 does, well their is a difference when i enable and disable crossfire anyway :laugh:


    been snowing like hell in Brighton today, has just stopped, have -4.3.c on a calibrated temp gauge :eek: damn cold out their

    EDIT: sorry to hear about your 4870 freedom :( hope it works out :D

    my rooms FREEZING without my missing 4870....its usually fairly warm in here but 1 4870 doesnt cut it....

    damn you global warming maybe I should turn the fan on my remaining 4870 down so temps are sitting just under 50-60c - its just sitting above 40'c right now

    Do you mean off?

    If you do, your room will probably will colder as the heat will just stay in the case instead of going out in your room.

    Fans and heatsinks don't make things colder just move where the heat is.

    Im talking about the fan on the graphics card - not the ones on the case - got 5 fans on my 902.

    at first i thought global warming is doing this but when i think about it again,isn't global warming about temperature getting hotter and not colder?

    I know, reread your post though, you say

    "turn the fan on my remaining 4870 "


    It can mean two things, either changing the fan to suck or blow depending on how it was before, to TURN the fan.


    Or to turn the fan ON, which makes no sense, why would you have it off :laugh:


    Science lesson Kuro!

    Warm whether causes cold wether, heat turns water into water vapor, water vapor turns into clouds, clouds block out sun, temperature drops.

    so if the planet gets TO hot then we block out enough heat ( like a reverse blanket) that its cold enough to snow, and snow reflects light making the situation worse.

    The last major ice age had a global warming before it ;)



    Not saying we're having an iceage now though, its not been hot enough to cause an iceage yet.

    Sorry for simplified explanation, I'm better ex explaining things vocally, by writing skills are sub-par!

    Every ice age has had warmer environments beforehand - the temperatures on earth are in a constant cycle going from hot>cool>ice age>warm > hot etc and has happend a lot of times throughout time.

    We are still on our way out of a mini-ice age in medieval times too :)

    As to the problem of your room being too cool you need to get yourself a 4870x2...that'll make things nice and toasty :D

    sorry, my hands get so cold they wont type correctly so I missed out words - but you were probably reading my erroneus post while i was in the middle of making the edits.

    If i turned the fan off - I dont think the card would just sit at 50-60'c come on, its common sense. but the idea is, turning the fan down so it creates more heat & so my case fans exhaust the warm air out meaning a warmer room.

    thats been the general thing 'to do' when it gets cold every Xmas - if its cold i boot the pc on & it warms my room.

    X1800XT & 939 CPU = very hot
    8800GTS (G92) & O/C X2 3800+ = fairly hot
    2x4870's & O/C 9550 = very/fairly hot

    Heatwaves suck - I remember that 1 summer when I had a FX-55 clawhammer & the X1800XT the GPU started artifacting because my room gets so bloody humid & stuffy in my room during the day & at night partially because I have hot water pipes right underneath my floor so it kinda 'bakes' the carpet...

    at night it gets real stuffy because I keep the windows closed as I tend to have problems with Mosquito's since my room faces the garden,

    it got so hot on my FX-55 that I was literally worried about it & also my X1800XT which was hitting 70'c-90'c even with the fan at 80-90%

    resorted to running the pc with the sidepanel off but that didnt really help an aweful lot so in the end I just forked out £300 for a tripple fan waterkit which pretty much solved the issues. but my mobo would still report chipset/VRM temps cuz that wasnt included in the loop - but it was great while It lasted anyway.

    That's not hot it works fella XD

    It doesn't create more heat, you move the heat out the case into your room faster by turning all fans up to max!



    How ever my case has an interesting effect when I sit next to it, it moves so much air that it pulls WARMTH from me then dumps that in the room instead.

    Get so cold unless I'm wrapped up lol

    ummm It does - & turning all the fans to max would mean the pc 'syncronises' with the current room temperature because the parts inside dont even have time to heat up.

    turning all the fans up just makes the pc cooler & 30x more noisey so whats the point of just moving cool air around for the sake of moving it??

    as i said - my 4870 is sitting at 45-40'c tuning the fans up would mean it goes to 25-30'c & that means no heat & if there is any heat being exhausted outside the case then its probably gonna take a while to warm my room up

    The components generate the same amount of heat no matter what speed the fan runs at, up the fan speed and it ejects more of the warmth into the surrounding room.
    I don't even use central heating in my room in winter, I just whack the PC on and downstairs my dad whacks the plasma on, if it's really cold he'll leave the PS3 idling.

    how can you say it generates the same amount of heat no matter what?? if you turn the fan up - more cold air gets pushed across the HS thus keeping the hardware cool or cooling down to a point where it generates little to no heat and at the same time freezing cold air is being vented into & out of the case.

    Or it could be that my parts dont heat up that much at all

    Quite fine, I've had to explain to my dad how it works that many times that it takes a couple of seconds to explain it now!

    Think of it this way.

    100ws of heat is in the head of a pin, you touch that pin to someone and shit damn it will burn them.

    Now imagine teh same 100w, but like something the size of an average heatsink, now its cool to touch even though it has the same amount of energy.

    When you use fans or heatsinks this is what you are doing, putting the same amount of energy over a greater area, be it the air or be it a heatsink/water what ever.




    So you see things feel colder because the amount of energy is distributed over a greater area.



    SO having a big heatsink + fans on high speed, will make the process more efficient, even though the processor is still generating x amount of heat energy.



    Sorry if this is confusing, I can't write for shit.

    Think about it like this:
    The heat produced is a gas produced in a chemical reaction.
    The efficiency of the cooling system is the diameter of the tube leading out of the reaction container.
    No matter the diameter of the tube the same amount of gas is produced, however in the same amount of time a smaller amount of gas would be released through a tube with 5mm diameter than a tube with 10mm diameter.

    Well you certainly do have the explanation down to a tee, nice and simple!

    Can't hopefully that makes it clear.

    I'd be happy if i didn't have a couple of deliveries due today and if my car isn't booked in for an emergancy recall fix tomorrow...

    Still when i look outside i see this:
