CPU fan suggestions

[Novex]

I am looking for a fan that is much quieter than the delta but with similar performance. Is there such a thing? I dont mind the noise, I have gotten used to it, but my family cant stand it especially when there trying to sleep. I have my door closed and it still wakes up my mom through the wall. I want to start leaving my computer on 24/7 but cant with such a load fan that wakes everyone up. I dont care how expensive it is because fans are generally cheap, but I dont have enough money to water cool.

Im looking for a 60mm fan

I know you are looking for a 60mm fan

but you might try this (http://www.overclockers.com/tips619)

thanks for the idea, but I take my computer to LAN @ my freinds house. It would be harder to transport, and it doesnt look that good. anyway I dont have dreamel to cut a hole, but i could buy a nibbler. Where would I get one and how much are they?

Mabey I could change the design to have the blower in the back of the computer, then duct it to the CPU. Also have the blower detactable some how.

Does this sound good? but id rather just have a quieter fan and not have to do this much work.

They have a good selection of fans at www.sidewindercomputers.com. You can even listen to the fans online! They are also a super company to deal with.

the Zalman Flower heatsink (comes with a fan) has very good cooling potential and is very quiet - as quiet as the Intel retail heatsinks

I have bought stuff from sidewinder computers before and recieved very good service.
If I were to buy their fan adapter for my heatsink, what 92mm fan would you suggest? I would rather do that then the mod with the blower.
Also, would wieght be a problem with the big fan. I know there is a max weight that the sockets can support, and the CPU can handle and I think its on the AMD site, but since the wieght is at the end of the heatsink wouldnt it be less?

If you dont understand what im saying then I can reexplain it, or even draw a picture.

What heatsink are you wanting to put it on?

You could try the 7 volt mod which will make your fan less noisy and spin slightly slower by giving the fan 7 volts when it normally will get 12v. I did this w/ a volcano 6cu+ that was very noisy and the niose level dropped and I only saw 2C increase in temp. Look on any search engine "7volt mod" and you will find instructions. By the way it is easy to do.

The heatsink it will go on is a Thermosonic Tech Thermoengine.
P/N: V60-4210
Wieght: 258.6 g [heatsink only]

I found a site that has the volt mod. You can see instuctions
here: http://www.overclockershideout.com/7voltmod.shtml

Ill try that, but I first need to buy the nessisary things.

As I recall, that heatsink is very sensitive to air flow. On the other hand it has a free flowing design that presents little static pressure. That means that your best bet is to adapt a larger fan to it. Unfortunately that heatsink is also taller than most, so you may have some space problems.

Your best solution is to construct a cheap duct and use an 80mm or bigger fan. You can construct a duct out of dryer hose cheaply. Use 3 inch hose hooked to the heatsink, and then 4 inch hose to the 80mm. You can buy a cheap adapter between the hoses. The entire duct should set you back only a couple or three bucks. I ducted my Thermoenging to the rear case fan until I got my 8045 (which is also ducted to the rear fan).

The quickest solution is a 7 volt mod on the Delta fan, but I think you'll find that you get a substantial decrease in performance. Still, that may make mom happy enough while you work out another solution.

I was going to duct it, but should I have the 80 mm fan mounted on the heatsink and ducted to the back or the 80 mm fan on the back of the case and the heatsink bare with the duct between them?

Umm that's a very nice set of instructions and all, but you really don't need to buy anything at all. It's quite simple really.

Basically, without cutting any wires, just carry out step 6 on the 12 volt return and the +5volt wires (identified at the end of the instruction like you gave.) Now put the +5 volt wire where the 12 volt return used to be. Rather than reattaching the 12 volt return wire, I'd put a piec of tape on the end to protect it and to remind yourself that it's been modded. This is a better method because it's easily reversible if you decide you want 12 volts again.

The basic idea is that the red wire from the fan should connect with the red wire from the power supply. The black wire from the fan should connect to the yellow wire from the power supply. Everything beyond that is just frosting and elegance.

With that heat sink the fan should be on the case and the sink should be bare. There isn't a good way to attach an 80mm directly to the sink, and there's no sense using an adapter if you're going to duct.

I have desided on what im going to do about my cooling. Im going to buy 2 sunon high speed fans and duct one from my heatsink to the back of the case. Then run my IDE cables under my motherboard and add the other fan on the front with a filter on it.

Would there be any problems with cutting this down and putting it in my case?

How would I attach it to the heatsink and 80 mm fan?

[Garfield]

I'm going with 4 Sunon 80mm High Speed fans for the case. Many people have a lot of nice comments about this idea, especially for noise and OCing. Just thought I'd share this with you :D

Well *I* used 3 inch vinyl dryer hose on the sink, 4 in vinyl dryer hose on the fan, and a plastic size converter between the two hoses. The vinyl hose stretches a bit, so I was abit to get a good fit on both ends.

Other people have built ducts with cardboard and duct tape.

We could go into all the details about what makes the absolute best duct (hint, dryer hose ain't it), but for me the thing was to get something up to begin with and then worry about improving it once I had some experience.

Oh, here's a picture the black thing is the converter.

Bit overkill really as nihili pointed out. A 7v mod takes about 30 secs and a pair of tweezers - switch the black and red pins over in the plug.

Aren't there "special" fans that are made for heat sinks? Maybe you could buy a part (in your case, the fan) for a heatsink. I don't know.

[RnPgrosz]

Butcher is right, you don't need any tools that you wouldn't already have. I used small flathead screwdriver to get the pins out and that was it.

[JFettig]

id be careful about that 7v mod, try it on something other than a heatsink fan. because my old psu wouldnt let me do it and it'd just shut off... and if it didnt shutoff and just kept going without the fan youd burn up....

and some fans wont start on 7v

i made a switch on my fanbus to go from 7 to 12 but for some reason 7v was also off? dont know why it was all connected and all.....havent quite figured it out yet,...havent really tried much either...

[Novex]

Your right, I didnt need any of the stuff I thought I needed.
I spend most of the afternoon measureing and cutting a duct made of cardboard. I used a Cherioes box, scotch tape and a old 80 mm fan I found lying around. I have the fan blowing in onto the heatsink. The noise is cut down more than half as loud as before. It idles 5 C degrees lower although the max load went up a few degrees.
































:o :p

PICTURE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[Strangelove]

Hmmm if you are going to use at duct , might as well use at 120x38mm Fan runing at 7V that will give you a masive airflow at low dB

[Novex]

I dont have a digital camera, but I can borrow one soon. I should have it monday or tuesday.

[Novex]

OK heres some pictures of the duct.
