alright ... being sick to death of my Tornado, and after reading bits and pieces on the net i picked up a 7000A-Cu recently ...

2 questions...

1 - I have an nf7-s 2.0 ... I know it wont fit but if memory serves it can be modded to fit .. couldnt find the appropriate thread though .. anyone have exprerience with this ????

2 - The tornado is attached to my beloved slk-900 ... how much of a temperature rise do you think im looking at here ... i dont mind backing off on the overclock (2500 @ 2310mhz) a little .. ie to 2200 or so just for some peace and quiet :D

any help ?

    I slowed my tornado down to about 5000 rpm and the temps & decibals were ok but I can't give exact numbers ...

    Why not just put a different 92mm fan on there? One that operates at 2200 rpm or so? Temperatures will rise quite a bit, but you shouldn't lose more than 1-3mhz on the fsb.

    On the tornado, why not 5v or 7v it? Perhaps you could buy a rheobus? I have an slk947 + 92mmTornado + Vantec Nexus fanbus. Does an excellent job with speeds. The lowest you can run the tornado on it is about 2500rpm. My 1800+ @ 2206mhz 1.7Vcore runs at 51C, but my ambients are terrible (around 29c damn midsize case and excess psu cords). I've got a midsized Lian Li Pc61 and an Enermax 651P-VE which has millions of long cables.

    You've got a lot of options, but I don't think it's necessary to pay $40 for a new heatsink.

    As for modding here's what I found:

    Here the nf7-s was deemed incompatible, hrm

    In a nutshell, you will be able to get it to fit, but you'll need to modify the heatsink mounting assembly. I had to do this on mine so it would fit on my NF7-S.

    All you have to do is this. You'll probably need to file the heatsinks mounting foundation, there are two, one for each side. If you need to do this, it will obviously only be the one at the top (on the picture) you'll need to file, so as it will fit onto the motherboard without touching or putting adverse pressure on parallel capacitors and what not.

    Even if you don't need to do that you'll definately need to shave down one side of the heatinks main securing clip. This really needs to be done on a grinder so as you don't accidentaly puncture through the hole on the end of the clip necessary to secure the heatink to the foundation assembly (there are two holes, you only need the one closest to the HS for socket A installations). You could try and file it, but it's tough metal and would be more trouble than it's worth. Once you've done that, the heatsink will fit securly and snuggly without risking damage to any of the surrounding motherboard components.

    All that might sound a bit daunting but it really is easy as pie. If you do decide to go for that combo, feel free to PM or email me if you need more detailed assistance.

    I posted a brief guide on how to mod the 'Zalman 7000A-Cu' in the above thread. If you need anymore assistance, just PM or email me.

    That Zalman cooler, cools my 3200+ running at 2.2GHz just fine, and I don't even have the fan running at max speed. It should work nicely on your system, and it is dead quiet, even when the fan is on max.

    Cheers

    alrighty, will try the 7 volt mod first, then will look into grinding the mounting assembly on the zalman ...

    thanks much guys. will report later

    oh .. incidentally .. current temps under full load:

    CPU - 38 C, Ambient 26 C

    will report temps too after mods

    mondi had this to say
    CPU - 38 C, Ambient 26 C

    The Zalman won't be as cool as that.:p But yeah, post back when you've done some messing.

    Definitely try the 7v mod first on that Tornado. 7 volts is still plenty enough voltage to insure reliable startups on the fan but should cut the fan speed down quite a bit, which lowers the percieved noise levels much more than what you would think. That is mainly due to the reduction in blade tip speed due to the lower rpm's. I bet that Tornado on 7v will be only slightly louder than a regular Sunon case fan, with none of the whine noise like it presently makes.
