Cooling fastest 120mm fan? (UK)

basically im after a fast 120mm fan to go on a xp120 to try and lower my idle temp a bit. the one ive got on right now is 1800rpm, now im just wondering if there are faster fans out there? im not too bothered about noise as when i have the pc on im usually listening to music or playing games etc.
any help would be great

thanks

 

The one at the bottom here should do the trick nicely. You might need some earmuffs, though . A more reasonable alternative might be this model.

 

it wont be quiet though .. 59 dBA

 

I'm sorry, but what temps are you getting?!? If an XP120 on an Athlon 64 doesn't get you good idle temps, something is not right, and it's not the fan...

 

The delta's are awsome have the 120mm one here Kicks out LOADS of air at 12v, (but you need earmuffs) at 5v airflow is still decent and noise levels are much better....

 

cheers guys.

@nexxo, it idles at between 33c and 37c, and its going up to about 50c under load, this is with a slightly increased core voltage to around 1.42v to get to 2.4ghz OC.
i do have to have the xp120 installed upside down as if not it will foul the first DIMM on my mobo.thats probably the problem but it cant go on the other way round

 

I suspect the heatpipe is not working then and no fan will help that, so unless you manage to turn it round I would invest in another HSF and that will probably work better!

 

The orientation of the heatpipe won't affect it in any way. The liquid inside the heatpipe will evaporate and move away from the heat source, cool, condense then and return to the heat source.

 

No dude some heatpipes use gravity to return the liquid to the base - vapochill micro for one, it evporates rises to the top then re-liquifies and gravity returns it to the base in some cases?

 

The condensed heat transfer liquid does need to return to the source of heat, which is done by its movement through a "wick" that lines the edges of the heatpipe. Correct me if I'm wrong, but as far as I know, capilliary action alone is not sufficient to transport the coolant back - gravity is required to move it the full distance.

 

Heatpipes only work in one direction. Just look at the Asus A8n-sli Premium in a Lian Li V case.

I would go with a silverstone fm121, and a fan duct for eliminating the deadpsot.

 

Heatpipes work irrespective of gravity, and that Asus board will work in a Lian Li case.

Idleing at 35 isn't a problem, my 3700+ idles at 49-50C

 

I agree with phuzz here: I don't see what your problem is. You've got temps that are very good for aircooling under overclocking conditions. Remember that an Athlon 64 will chug along safely up to 75c. I think you are getting anxious for no reason whatsoever.

On that note, I'm not sure what people are thinking these days. Everybody "overclocks 'till it locks" but still expects their CPU never to exceed the upper 30's C in temperature. That is crazy talk. CPUs run safely up to the 70s C, and when you push a CPU beyond its specs you have to accept that it runs warmer than under stock conditions. Under air cooled overclocking conditions, a max. temperature under load of 50C is perfectly acceptable.

 

There IS a orientation to heatpipes.

If you take the A8N32 and turn it upside down it WON'T WORK. Why? Because the fluid evaporates from say the south bridge or from the north bridge only to move UP towards the southbridge. When the voltage regulators are where the mass of the fins are. that's why heatpipes have an orientation. The finns where the heat exchange takes place MUST be on the top so the hot liquid can exchange the heat and condence. Now, if you've got your A8N32 upside down, and the heat exchangers are the Voltage regulators on the bottom, how do you expect the heat exchange to take place since gases are lighter and the go UP?

 

The orientation doesnt matter because the gas will, by nature of gases, take up all the space it can and reach the cooling side. That's how they work at any angle, and how my SI-97, the heat sink that's completely dependant on heat pipes, is working (and doing a terrific job at cooling my new processor) right now.

 

From Neoseeker:

From The Heatsink Guide:

However we can test the effect of orientation on fullfat's setup quite easily, by getting him to run his PC on its side. I personally doubt he'll see any difference in temperatures, though.

 

Given the number of heatsinks with a U shape heatpipe and the most popular orientation for such heatpipes would be on there side, I doubt theres any noticable effect at all from the orientation.

 

thakns phuzz/nexxo,
this is my first time overclocking a cpu and using a higher core voltage so im just being over cautious i guess, when youre reading forums on tips and results from other peoples rigs, its the 'too many cooks' syndrome i guess.
i wasnt aware that amd64's could go up to 75c i thought the max temp you should run was 55c really hence me getting anxious about me nearing 55c with the overclock.

 

To find the temperature limit of your particular chip, download A64MaxTemp and give it a run. You should want to keep at least 5°C under this temperature at maximum (i.e. dual Prime/3DMark) load.

NB: The MaxTCase application is only usable on Revision E processors - you'll likely have one if you purchased within the last few months.
