[Vapor] IFX-14 vs. Ultra-120 eXtreme (and others!)

[Vapor]

I have an Ultra eXtreme arriving in a day or two.

For the sake of saving me 20 minutes of digging through charts and pages, would you be kind enough to answer the following question, Vapor?

Which fan is the quietest (relative term, I know...lol) between these 4 you have listed:

• Sharkoon 2000
• Panaflo M1
• Sanyo Denki
• Delta GHB

The Ultra 120e's temps look damn good with those 4 fans.
If I were going to purchase one, could you make a recommendation please?

Sharkoon Silent Eagle 2000. Really, any 2000RPM fan will get around the same cooling as past 1800RPM the U120eX scales much slower. It is pretty quiet for a 2000RPM fan though.

What was room temp for your experiments and how did you hold it constant? I have found that room temp has a huge affect on CPU temps so some of those close results might be misleading if it was a few degrees hotter in one test vs. the other.

Ambient hovered between 22.8 and 23.1C for most of the day. Though the earliest tests had ambient as high as 24.9C. I did retest the Ultra-120eX with the 800RPM fan after ambient dropped and got a dT within .1C. A/C was on and ambient temps were measured with a DT200.

To be honest, in open-air testing, I have not noticed the same ambient vs. CPU temp trends you show in that thread (and I've done a lot of CPU-temp tests in the past year). I've noticed that higher ambients give SLIGHTLY higher dT (like .8C-1C for a 10C increase in ambient, in two separate tests, two different HSFs), which is probably due to a smaller fin to air dT, reducing radiator efficiency. In-case testing I've anecdotally noticed slightly more of this effect, but 'ambient' was room temp, not case temp (I have a feeling case temp goes up by a little extra, and then CPU temp gets an even higher ambient because of it).

So you're saying with a B3 stepping Quad core at 3.2GHz and 1.39V load Vcore, and maxing all cores ala Prime95 but instead using Orthos, the averaged temp core as read by CoreTemp 0.94/0.95 is around 85-95C? This is what appears to be the case if one takes the base temp you report of 47-65C and add the 23C ambient temp.

I have a question, did you tough the heatpipes and base during testing to see if they're warm or hot? Perhaps they're not transferring heat well. Just a thought but perhaps they didn't fit them with liquid?

I say we should be seeing temps about 5C less than the TR 120 Extreme or better.

Yes, the whole HSF was actually very hot to the touch; heatpipes and fins. What little air was coming off of it was also hot. As airflow increased, the HSF cooled down accordingly (by 1600RPM, it was tolerable).

An 800RPM fan is really not a lot of airflow for HSFs like these. The high temps shouldn't be a surprise at all, IMO. At one point, getting to see 96C on two cores was a bit of a shock, but overall, averaged temps above 90C are there and are reasonable.

I expected better temps than the Ultra-120 eX based on the design....but oh well.

thanks for sharing ur results Vapor, is it possible to add an ultra-x to ur tests

Not really...I have no use for another HSF, so no reason to buy one.
