CPU HSF funnel

I just got a new Cooler for my video card and silent 120mm for my case and now my system is pretty quiet. The only noise now is my CPU fan. I have an extra 120mm fan sicne my case didnt really need 4.

I have a 2 heatpipe AMD cooler. Is there a product that will bridge the 120mm to fit a cooller like the one I got. I remember hereing about a funnel that works with 92mm fans, but I can't even find that any more.

Also on my motherbaord the chipset is right next to my CPU if I mount a 120 mm on the CPU HS and the rest of the fan was hang off. First would it cool the CPU right? Second would it cool the chipset if it was right over it?

Thanks
 
I wouldn't try 120 to 60. 80 to 60 is a pretty big step alone and you will need a pretty strong fan to overcome the back pressure (fan adapters with funnel-shaped throats) even with that step. Many experiments with 80 to 60 adapters have failed to achieve any improvement and even degraded the cooling some due to the back pressure. So I'd suggest trying the 80 to 60 with a fan like the Silverstone FN 82 or FM 82 which puts a 90mm fan onto an 80mm mounting. Or else get a heatsink that can use your 120mm fan directly.

SVC. jab-tech, Nexfan, sidewindercomputers, thermalfx, etc. (all www.______.coms) all carry fan adapters and an array of fans (buyextras is another good source for fans) but Nexfan currently carries two types of 60 to 80 adapters for the best prices available (I'd try one of each) - but they are hardly worth paying shipping on. Maybe you could find a fan or two there or something else you need to justify the shipping cost. Unfortunately they carry few brands of fans. The Evercool 70x25 fans I bought there are very nice though. They also sell thru eBay and you might save a few cents going that way.

Generally you want ball bearing fans for use on CPUs - but sleeve bearing fans can work too but it is better if your CPU fan will be working in the vertical position for sleeve bearings, while ball bearing fans work well either vertically or horizontally. Also try the CHEAPSHIP coupon code at Nexfan as that is supposed to give you a $5.00 flat-rate on shipping. Perhaps just those two adapters would yield a lower shipping total - try it both ways.

The fan on my CPU is either a 70mm or 80mm. I found a single adaptor for both sizes.
I just have to figure whick one fits. The problem is the fan seems to be 70mm but he brace holding the fan seems to be made for 80mm.

Look at the picture and see if can figure it out.

Thanks
 
That AMD retail cooler has a 70mm fan though the heatsink itself looks like it may be at least 80mm in one dimension. The reasoning for the smaller fan is that you don't want the fan blowing directly on the heatpipes as the medium inside uses the heat to help move it thru the pipe so you want to reserve the fans output for the medium that is already within the radiator. The fan looks like it is only 15mm thick. Nexfan has a really nice Evercool 70x25-mm unit that will improve cooling while keeping the air where you want it - I'm using one on my heatsink that also came with a 70x15 that was fairly strident at full speed (I hook my fans to a manual controller and I've been able to crank these 70-mm fans back to where they aren't bothersome while still cooling adequately). I wouldn't use one of those open-frame multi size adapters on this heatsink. Use an 80 to 70 funnel type if any.

With some further thought, I see that you could try a larger fan or fan with adapter if you offset it so that it is blowing onto the cool side of the heatpipes (you can tell the cool side from the warm side by touch. However, if your heatsink maker doesn't control the flow direction in some way, you could have both cool and warm pipes on both sides. So you would need to check it over a number of on-off cycles to be sure the flow direction is consistent before using the offset method.

If you're wanting to make it quieter, I'd suggest just getting a different CPU cooler such as the Arctic Cooling Freezer 64 Pro. A few places have it for under $20 (plus shipping) and it is already a reasonably quiet design with a 92mm fan. It will probably cool better than that AMD unit you're using and be quieter.
 
I guess I could but I'm being lazy (and alittle careful) and dont want to remove my mother board to attach the HSF. And really dont like put new heat sinks on since it feels like i'm going to break the cpu every time I do it. My system is M-ATX board (case is a tower) so it very tight. Also from most of the test the stock heatsink is better them most except fot the huge ones. I dont want them in my case.

Plus from what I here the Arctic Cooling Freezer 64 Pro doesn't cool any better is lounder when its cooling at the same rate. Just going to get my funnel 🙂

I will post how it worked for me when get it.

Don't know where you heard that, unless it was comparing against the quad heatpipe AMD heatsink with 80mm fan.

The AC Freezer Pro 64 is pretty easy to clip in (as long as you line up the bumps) and uses the stock mounts, so no need to remove the motherboard. The clips can be oriented in any direction in 90º increments, so you can orient it so the fan points wherever you want (usually towards the back exhaust fan) and orient the clip so that the part you press down faces away from the PSU for easy installation.
 
ok might go for the artic freeze. I just built my GF a new C2D system. IT was barebone system and had a BTX cooler in it. Its crazy loud. I got up last night to see what the niose was and it turned out to be here system in the den. That about 35 ft away in another room and i could still hear it. Very few places sell the funnels and and none of them sell both a funnel and a BTX cooler. So i might just get the Artic from the same spot that has the BTX cooler.

My laziness showing through again 🙂
