[citation][nom]nforce4max[/nom]Zoom zoom zoom. I am not a big fan of passive cooling. I tried with a single 9800gt, it heated up to 121c. Needless to say I went back to active cooling.[/citation]
Passive cooling relies on the native airflow of the case, rather than having an onboard fan on the card. Your card heated up so much (most likely) due to poor air circulation where the passive unit was.
Thats ridiculous! I am sure that will take up more space in your case, i could be wrong. BUT that thing will increase temperature in your case! they should focus on a cheap water cooling system. I like the original HD5000 series cooling method.
[citation][nom]jasonpwns[/nom]"the cooling system resembles a car's radiator grille"Not the full radiator, learn to read the article and not just the title.[/citation]That's right.. this is the only cooling fin arrangement made that resembles a car radiators fins, right? I don't need to read the article. The title lead me to believe something else. This has happened on numerous occasions.
Gigabyte has been a big player in high performance with passive cooling. I've used such designs in their 7600GT and 7600GT. The big advantage is that there is 0DB noise coming from the card - okay, I am assuming that.
With a big case cooler fan, it helps to suck out the heat generated by the radiators.
As shown on this ATI5770, the 2nd slot is used as an exhaust vent. This CUSTOM design use used by Gigabyte and looks very much like my 7600GT from years ago... and it was HUGE back then.
For heat issues, I switch to BIG-FAN coolers like HIS graphics cards which come with ICE coolers, which I had before my 7600GT. My 4670 is ICE and silent.
Paid $180 for my 7600GT - Passive and $80 for my 4670
[citation][nom]slickyfats[/nom]Looks great now (hopefully performs great too). But put it in a standard users case for a while and you get to spend 2 days cleaning all of the dust out of all the individual fins.[/citation]
this is why air duster cans were invented...prob solved
[citation][nom]aznguy0028[/nom]this is why air duster cans were invented...prob solved[/citation]Or in really bad cases (dust + smoke = super caked on dust/sludge) I use CRC's Lectra-Motive. In the garage or driveway, mind you.

Seriously?!? have you ever actually CLEANED anything with a can of air. Probably not. I have a Zalman 9700 and the fins on it get caked with stuff that will not just blow off. So your "problem Solved" isn't really.
Instead of air duster, I used leaf blower for my garden to blow the dust out of the case. This should only be attempted outside of the house. You'll be surprised how much dust will be out of you case with HUGE VOLUME of AIRS =)
Agree. Cleaned out my brother's 4 year old Athlon x64's heatsink and a silent graphics earlier this year. I resorted to wrapping a square of toilet paper around a business card and using that to pull the dust out from the fins.
