    i recommend the new zalman heatsink and fan combos. They are exteremely efficient, and if your'e not number crunching all day or playiing Unreal , they run in silent mode too. Although they're not cheap (£30 in the UK), They do look a little special, especially if you want something that looks trick....
    Go to the bottom of this page to see them

    I've got one in my system although i did struggle to get it all in my midi case.....

    I would love to simply win one!!! ;) I've been looking but all the contests giving them away seem to be over. Anyone know of a site that is having a giveaway or contest like our beloved 3DS???

    Cheetah, 30-40 bucks will get you a Volcano 7+. Just dont drink any beer all next week and you should be all set.

    LOL :)

    Yeah, I know I need to get a quality one, but I'm just lazy and a little intimidated. I'll get one that Volcano 7+, I've heard lots of good things about it. I've also been thinking of upgrading my chipset fan because I think it's hindering my overclocking ability. I was thinking of get this beautiful little baby.

    Any of you guys got any better chipset fans I might want to look at???

    Well, you may want to get the HSF first and see how much room you have around the chipset before you invest in a cooling kit for it. I bought a Swiftech 462 and a TT Blue Orb kit and after installing the Swiftech I didnt have enough space to install the Blue Orb kit. Your mobo may be layed out different from mine so you may be all set..Just a word of precaution.

    Hmmm...I think your right svtcobra, my chipset is pretty close to my current heatsink. I think I'll heed your advice and hold out on the chipset fan for now. It does look nice though...

    They do look nice in there but I also wonder just how much performance you'll gain in the oc'ing arena with a fan on your chipset..

    Don't really know cobra??? I still think it runs too hot though so a little more cooling never hurt. :)

    Plus it looks really cool!

    As long as it adds a certain level of functionality then it may be worth it..I probably could have modified the cooler I bought to fit on there with my HSF but I didnt think it was worth doing so.

    Hey Super,

    I just picked up the thermal take volcano 6 cu+, it has the big 7000 rpm fan, it is going on the 1900+ that has been sitting on my desk for a week now. You want my volcano 5 ??

    An interesting proposition boeing...how much you willing to part with it for??? If you want you can PM me with some specs and price.

    Thanks for the offer!!!

    The best HSF by far is the thermalright AX-7 with 80cfm delta!!!

    Sure aint the quietest with that 80cfm Delta!

    Heat sink guide

    Haven't seen it here yet but here is a good page I found with tons of Heat sinks and other cooler advice and stuff. Alot of the stuff we have talked about here in one stop. Enjoy.

    That's debatable. From my experiences, it seems much easier to blow heat away than pull it away. I think a faster fan is required to get the full effect of fan reversal.. For example..

    I put a 7200RPM delta on my copper SK6 heatsink backwards... My CPU (Athlon XP 1.33Ghz) locked up in a matter of minutes.

    I turned it the proper way, my system idled at a 33*C, which to this day is a temperature I rarely see with my 4500RPM fan.

    I went from a non-reversed Delta 7000rpm fan on my Thermalright SK6 to a reversed Y-Tech 4500rpm fan and only increased temperature by about 3-4 degrees celsius.
    I found that blowing down on the SK6 has been quite efficient for my cooling on my Athlon 1.4Ghz @ 1.5Ghz. Saying that I haven't fought with the SK6 clips to try it the other way round to see what sort of temperatures I get....

    I was refering to his exhaust fan, not the CPU fan.

    That's what I get for skimming instead of reading. ;)


    SuperCheetah: I use a Thermalright SK6 heatsink on my Athlon XP 1.3Ghz. I couldn't be more happy with how it performs. Coupled with a decent fan, it's extremely capable, not bad looking and not extremely heavy.

    I think the efficiency of pulling air away may be affected by the design of the heatsink and fan. It does sound logical to pull hot away away, rather than try to blow it off... But it might require some specialization.

    That is true Rick, but there are those who will argue the other way. Though I'm not one of them. I think you know of my adventures in cooling. If your fan has the power to pull the air away then it is much better than just trying to blow it off of the heatsink.

    So let me get this straight. If you have a fan blowing air away from the chip, then your temps will be higher or lower??? I assume higher, as it takes more fan power to suck the air away from the chip. This does make logical sense as the right way to have it, but I can't say I've tried it this way yet. But if you have to have such power to suck the air away then it kinda defeats the whole purpose of lower temperatures in the first place. Maybe I could design up some mod to do both at the same time. Don't really know how that would work, but I'm sure I could figure it out.

    Any more comments on blowing air on or sucking it off the chip? I'd really like to know which way works better and allows for better overclocking abilities. Thanks for the many comments on my question, you don't know how helpful you guys have been. Much props to 3DS and the great members it has!!!

    I think this greatly depends upon the design of your heatsink and fan.

    As I mentioned above, when I turned over (reversed) a 7200rpm Delta fan on my SK6 heatsink, it overheated within minutes. This is also without any appreciable CPU activity... Just sitting in the BIOS not doing a thing.

    When I turned it the right way (non-reversed), I had a temperature of around 33*C.

    However, if I am not mistaken, there are heatsinks that require a reversed fan to work properly. So reversed vs. regular fans is a topic that is very debatable.

    I think the Delta is probably too powerful to be reversed. Not sure though, I was just real happy to get rid of it after putting up with it for a few months...
    As previously stated I haven't had any problems with my SK6 and reversed 4500rpm Y-tech fan. I guess the blowing onto the heatsink must cool the copper base in conjunction with blowing any heat in the air away from it. The SK6 design has loads of fins mounted which I think helps with the channelling of air being blown away from the heatsink.

    Long thread & deservedly so. Lotsa good info. :cool:

    If I may: I don't think that box fan you having blowing across the mobo is magnetically shielded SuperC. I don't know the 'field' it disperses, but you might want to remove it & get some shielded/non-magnetic fans to replace it. ;)

    Pitch/contour of the fan blades will determine if the fan draws or blows, AFAIK. Ability to disperse the flow adequately (if it blows & is heatsink mounted) is dependant on the design of the HS. Cooling the 'sink doesn't necessarily cool the chip either. The heat from the chip has to be transfered to the 'sink 1st otherwise ... Compounds like 'Artic' are great for this, IMO.

    Just my thoughts & if I re-iterated anyone else (it was a long thread) just count it as 2nd'ing their opinion. :D
