Quiet CPU Cooling on 60x60 HS

[FiL]

I have an AthlonXP 1900+

cooling this i have a CoolerMaster HHC-002 pure copper HSF.

I think it uses the Delta 60x60 37.6CFM @ 46 dBA fan. I don't want to have this amount of noise 46 dBA!!!, but i don't want to reduce cooling power.

My motherboard will not fit a 80x80 heatsink, so perhaps i can gain extra quietness and cooling by fitting a 60 --> 80 fan adapter to the Heatsink and fitting a 80mm fan that pushes the same amount of air, but with quieter results.

for example i've found a 80x80 Pabst fan that does

40.6 CFM @ 32 dBA.

Now is using a fan adapter going to effect the ability of a fan to cool the heatsink? after all the fan will be further away from the heatsink.

let me know if you've had experience of doing this.

The best fans by far for 80mm are the <A HREF="http://www.thermaltake.com/products/dcfan/a1214.htm" target="_new">Thermaltake A1214</A>, a.k.a. the Smart Fan, and the <A HREF="http://www.thermaltake.com/products/dcfan/a1357.htm" target="_new">Thermaltake A1357</A>, a.k.a. the Smart Fan II.

The A1357 for example runs between 20.55 CFM and 17 dBA at 1300RPM at the low end and 75.7 CFM and 48 dBA at 4800RPM. There are not any other fans in the 80mm range that can beat them.

If you don't have access to buying one of them. You can use the Panasonic, Panaflo, FBA08A12U1A with a rheostat and drop it down to 2950RPM to get 39.6 CFM at 32 dBA. (100 grams, Min - 7 V = 24 CFM and 21 dBA, Max - 13.8 V = 46.9 CFM and 38.2 dBA. You can use the Paspt if that is all you have access too.

For attaching a 80mm to a 60mm base <A HREF="http://www.2cooltek.com/retro.html" target="_new">try this step by step</A> for the general idea. You will have to modify it for your CoolerMaster HHC-002.

You will need a 80mm grill, 4 screws that fit your heatsink (hardware store), four fan screws(might come with the fan or buy some), and the new fan.

You will have to attach the grill by putting four screws through the gill into the heatsink where the original screws held the fan on. From there you have to use four fan screws to hold the fan to the grill.

Tis is a better method of attachment than one of those funnel/adaptors. (A few reasons but I don't have time to get into now. If you want to know let me know.)

cheers for the info, i can't get any of the pictures on the 60-->80mm fan change link to work though

although i think i know what the article is trying to say...


so will i notice any cooler temperatures with the increased airflow of a 80mm fan? or is the size of the heatsink more important?

He has been having problems with the site for a couple of weeks now. Oh well.

You should see some form of improvement. If it is a 3C difference or a 10C difference I don't know. I don't have much experiance with that cooler or the HHC001.

In principle the temperature should drop. More air molecules will hit the heat pipe and the fins and thus transfer the energy away from the heat sink. So more air, better heat transferance.

heat pipe? the HHC 002 is NOT a heat pipe HSF....<A HREF="http://www.coolermaster.co.uk/hcc-002.htm" target="_new">http://www.coolermaster.co.uk/hcc-002.htm</A> but i'm just being knit picky now aren't I? sorry

I'm going to get some Artic Silver 3 and a quieter but more powerful 80mm fan...i hope to drop around 8 or more degrees to ensure 100% stability heat wise,

but at the very least it'll be quieter, and that is the most important thing for me

My Bad.... I was crossing the IHC and the HHC models. IHC is the heat pipe models. Call it a brain fart or a senior moment.

But both use the srews from the top of the fan to attach to the heatsink. So what I said to you earlier will work.

BTW: I contacted 2Cool and let him know that the <A HREF="http://www.2cooltek.com/retro.html" target="_new">http://www.2cooltek.com/retro.html</A> page is having problems. Hopefully he will have it back up soon.

Just skimming, you probably don't want to go with a 80-60mm fandapter. When these were first available and all the rage it was proven that by reducing the flow of the 80mm fan it actually reduces the cooling efficiency of the fan as related to a similar CFM 60mm fan. It has to do with the air pressure as I understand it.

I use a Thermaltake 60mm fan on top of my Alpha Pal6035, pushes 31cfm at 28db, decent airflow at a decent noise level. With your Cpu, I'd look at a Alpha 8045 or the Swiftech 462 and put a nice quiet 80mm fan on top.

Using a 60mm Heatsink with your processor and wanting a quiet fan to cool it will be near impossible, just my opinion. Anything over 40db is too loud for me.

yeah, it's just that my motherboard will NOT fit a 80x80 HSF, so i'm stuck looking at 60mm fans, or an adapter for 80mm fans. so maybe for quietness sake i should get a motherboard that DOES support a 80 x 80 HSF : ) perhaps i could get one that also supports the new features like AGP 8x and USB 2.0 as well while i'm at it : )
