is this product telling the truth?

[hyenolie]

look closely at the chart, theres a 20 degres drop in temp. i realy belive this is bullshit, there are many site that sell this item, and have that chart up there.

someone tell me if this duct actualy does that much better than regular hsf

My CPU is 32C at idle...why can't this duct do that?
My load is about the same as what they say for the duct too...lol 38C.
The red like is with the kit though. Those temps are very possible.

 

[hyenolie]

i konw the temps are possible but im asking does this duct do that? has anyone ever had a duct that made 20 degress of change? cuss if it did, im buying it.

 

[Asus]

The duct makes room temp. air blow on the CPU rather than air that has been warmed in the case for a bit.
There is a bit more to it than that but that is the main plus.

 

[hyenolie]

you think that there was ever a mistake when they accidently measured the temp of the air rather than the temp of the cpu core itself? is this possible in anyway? maybe the temp reader is a crapy one?

 

[RandomPING]

I thought it was bullshit too, but i've seen a couple other places review things like this and get massive improvements. Seems kinda strange, but aparently it's true.

 

[hyenolie]

do you think the tested without any hsf and then used the duct with a hsf?

 

[Asus]

hah no no.
They most likely used the standard heatsink/fan that comes with retail CPUs then added the duct...
The big help is the back 80mm fan that is also connected to the duct.

 

[crabcakes66]

you can got to your local hardware store and buy that ducting and clamps for about 4-5$

edit:nvrmind it doesnt even come with a fan....

 

[hyenolie]

i dont know what to do, i might get the zalman cooler first, if i dont get 35 load temps im going to just buy the spark7+ to go along with the duct, cus rabies has the duct and he says he hits 28 degres,

if this happenes then i might give the zalman cooler to rabies for all his help =D.

but he runs amd, so... n e ways ill still give it to him. im pretty shure ill find a answer im content with by the time i make my full purchases, rabies will help me.

Actually ducting your CPU really DOES decrease the temps by about 10-15 degrees, depends on your current cooling, case, casefans etc. And remember you can't trust mobo temps, as it isn't a probe recording the temps, it is done via a sensor that measures something wich then gets run through an equasion wich provides the temps, they may be off by 1-5 degrees, but it depends on what mobo you got and what bios version.

Duct cooling is a good idea if you've only got a couple case fans. I'm a firm believer in ample case cooling and tighty wires. You have to take into consideration that parts like your videocard, RAM, and to a lesser extent your northbridge are being deprived of all the air being directed over your CPU.

 

[hyenolie]

my case is a arcylic case, its got 5 80mm fans by antec smart fans thermaly controlled. not the plus version. its got two on the sides, 1 on the back, 1 in the front and 1 on top.

do u think this is a good setup? and that it dosent require a duct? most liekly ill be playing hl2 for about 5 hour periods minimum, after that ill be doing CS for another 3 hours and bf1942 for an gour or so. what do u guys think will 5 fans be enough? remember that will cool down the case, not the core, i dont want my core to be anything over 45.

Acrylic is an insulator, which is a bad thing, but 5 80mm case fans plus the one in the power supply is more than enough to than to warrant duct cooling. Duct cooling is not a popular option in the overclocking community.

 

[hyenolie]

actualy my antec true550 has 2 in the power supply =P,

will the duct mess up air flow?

Why isn't it very popular? Just out of curriousity. Seems like it could be pretty good if you had a pretty good Heat Sink and fan on the processor.

 

[hyenolie]

if it does the temps that is shown in the chart, 35 load, then why not use it?

 

[[Matt]]

my copper cooler and 60mm fan gets roughly the same temps as that duct fan... the black line on that chart must be a REALLY crap fan and cooler

 

[hyenolie]

i dont konw what the used prior to the duct, but if a duct gets 35 load temps thats great. i might buy that,

 

[Maxi]

Id get some more casefans and a better heatsink before ducting.. but thats imho. Also if you aren't ocing this is not nessesary. And why the hell are you digging up old threads for?

I wouldn't call a thread from a few days ago old

I use that duct cooler, my PC actually gives me a yellow light, in the case of Soltek Hardware Manager saying my temp is too low for operation. Green light means normal temps, yellow is danger, and red is fried. But when I boot I can boot at 25C with a yellow light, and stay that way until I start to use some load bearing programs. Then it will bump to 38C, when under a FULL load it will stop at 43C, and go no higher. I have found the duct cooler to be of most use when you have alot of obstructing wires or objects that emit alot of case heat that can get pulled back onto the CPU...

So you will only need it for direct air intake for the CPU in the case of obstructions or heat. Or if you want it to look tight... But my case is not see through so I use it for performance.

im going to try a home made version

Ducts are for wusses...

What you want is a VapoChill case. Sure, it's quite a bit more expensive... but when you need sub-zero temperatures there isn't much else that will do it for you (without short circuiting the CPU with condensation).

 

[hyenolie]

is 35 load to much to ask for? with nothing else in mind, im not trying to squeeze performance out or anything, i just want my 270 dollar cpu and 500 dollar vga to be safe, is that a problem? i am a little paranoid about this temp issue, thats why i post a lot of temp questions and take testimonies into account, a lot of people have told me that with my 5 fans, and a zalman 7000aCu ill be fine. should hit 38 at load, if i cant hit 38, then im going with the duct. is this a good plan?

Well I wouldn't go as far as saying they are for wusses, they are simply for people that have spent over $3,000 on hardware and cannot fit any more crap into their SOHO server case. :rolling:

I will admit that water cooling is the way to go, especially if you have a 64FX chip. However I prefer Swiftech for my liquid cooling solution...

Hyenolie, you can go to liquid, for a price... But if you are not looking for elite performance from water bricks or radiators, then stay with the Porshe design and keep it air cooled :thumbs:
