I'm thinking of putting a 2000rpm Kama Flex 80mm in my Antec EarthWatts 380W, so I wonder if you have tested at what voltage it starts? If not would you mind doing so? If it doesn't start at 4V do you think the 2500rpm might do that? What counts is, will the PSU circuit start it? So, spend some kro...

When I first saw this heatsink, I wondered why there is a section of fins "missing" on the sides. The stated reason is to improve the cooling of the mobo, as you mentioned. Another, possibly more important, reason is to allow a better/more compatible mounting to be used, allowing room for a screwdr...

What I would like to see is some common fan testing. SI-128 SE, XP-120, Zipang, the new Noctua, etc, etc, all with the same fan, same processor, and same board. Commonality in testing is such a great idea that nobody would argue against it, right? Uh, which can get from Long Beach Harbor to Avalon ...

I believe it was you who said in another post that a fan rated for a lower speed should be quieter than the same fan rated for a higher speed within the same series at a constant CFM/speed. Well, I thought so. But sometimes not, as my Slipstream500 vs 800 proved. Neil was right, 800 is the Slipstre...

Now that the Slipstream fans have been out in retail for awhile, has anyone done testing of the fans yet to determine if the CFM ratings were accurate? CFM ratings are based on zero backpressure. For any fan, as backpressure goes up, CFM goes down. Panaflo/NMB is one company that produces graphs of...

Just a few questions: How could it be that at 7.9V, the Kama Flex spins virtually at its rated speed? Secondly, it seems what you are saying regarding the Kama Flex is that because it has relatively high pitched blades, it is not all that well suited for high resistance. Is that a general rule? I j...

Here.

If you follow the link to Noctua, and then follow the link to the english-language review (dated today!), you will find some cooling performance figures with no fan that I find very hard to believe...

Direct link to cooling data here (no-fan data towards bottom of page).

Are these for real? The fans are real. The 19dBA noise spec, if meant to apply to the fan when it's turning 2000RPM, is absurd fantasy. Just as Thermaltake's 2000RPM Thunderblade 120mm fan has a 21dBA noise spec. It turns out that Thermaltake printed a minimum RPM figure in the Northeastern Oklahom...

Lessee - you have a 140mm on the Zipang, which is neither an intake fan nor an exhaust fan. It cools the Zipang/CPU, but not the case - it just circulates the air internally, just as the XP-90/92mm Kama Flex on my machine does. You have three intake fans, all 140mm, 2 of which always run. And you ha...

I doubt there's been much evolutionary gain in this regard the last hundred years or more, certainly none in the last 50. Human spaces are mostly devoid of non-human predators... and with the latter, it's usually less about physical sneakiness. Not if any of the extreme crime Am. TV shows are to be...

Here . Interesting little gadget. Hard to figure how the airflow works from this link. Anybody seriously interested should also read my review of the Nexus Frizzbee and the Logisys HC-100 in the User Review forum. These things do work, and do work quietly (sometimes needing a fan controller to adju...

Time wrote:Which socket is the K9F4G?

754. Sorry about the propeller - windtunnel mixup.

Now, in your humble opinion, which would you opt for today for a case fan - the 80mm Kama Flex or the tried and true Nexus? Under no circumstances would I ever use a case that's cooled by an 80mm fan. In general, where there isn't much airflow resistance - no filters, no HSF with tightly spaced fin...

Seeing as you have installed the GeminII before can you please tell me if you removed the plastic from around the socket? I used an Asrock K9F4G-Sata2 mobo and I don't recall any plastic on the bottom of the mobo. On top, there was the usual plastic retainer. It's been so long I don't recall the de...

Using the huge side fans on the Xclio cases to passively cool large-area HSs such as the GeminiII is a fabulous idea. I tried it, with two large-area HS cooling grids (GeminiII and Dominator(?)). It doesn't work. While large side fans (220mm and up) do indeed provide lots of quiet CFMs, they do so w...

continuum wrote:For 92mm, the Nexus 92mm's or the... crap.

The Nexus was a very good fan when it first appeared, but it's been around almost as long as the Panaflos. You might want to look, for example, at the new Scythe Kama Flex 92mms (1600 or 2000RPM nominal). Just a thought.

I just recently heard about these, are they any good? http://www.enermaxusa.com/catalog/product_info.php?cPath=28_30&products_id=101 From the specs it shows 17dba @ 1000rpm I assume? Isn't this pretty loud for something claiming to be noiseless compared to the other fans enermax offers which push m...

Have you reviewed the 80mm KAMA FLEX by chance yet? Is this the same 80mm fan that is on the recommended list, which is called the KAMA FLOW? If you ever looked for my reviews in the User Reviews forum (hint: look for 80mm fan reviews), you'd know the answer to your first question. I believe the Ka...

I just recently heard about these, are they any good? Be advised that the promoted "noise levels" in the US of A are total fantasy. In Italy, Enermax puts some actual measured (at 100% RPM) noise levels on them... which are vastly higher. I reviewed the Cluster (PWM) and Magma recently in the User ...

A friend of mine bought one for the Antec 1380 HTPC case. Despite the Shuriken's 64mm height and the 1380's reported 65mm clearance below the PSU, he could not make the Shuriken fit. He's now using a Thermaltake TR2 HSF, with a fan that's not centered, to clear the PSU.

AKA 3RSystems "Prima" HSF, it points toward the exhaust fan on most AMD mobos, which the Xigmatek does not. So that makes 3 brands pushing the HSF. I assume the SilenX will be marketed in the US of A.

The problem with the MaxOrb is its fan, designed to make the MaxOrb work with really hot CPUs. Most SPCR folk would prefer something a lot quieter. Oddly enough, almost a year ago three threads were posted about replacing the MaxOrb's fan with something quieter: May 19 2007: Here . Jun 7 2007: Here ...

With the 4850e, I was shocked that the heatsink was very warm (even on upper fins) after just a few minutes. I've never reseated the HS, and I'm pretty comfortable that I did that right. If the heat was getting to the upper fins quickly, then you definitely had the HS seated properly. Perhaps you c...

Here. 100mm, 1000 or 2000 RPM. Veddy thin. Lotsa blades.

The vast majority of AMD mobos have the CPU socket oriented so that most HSFs point at the PSU, not the exhaust fan. Two examples are are the Xigmatek HSFs and the Ninja revB (the extrusion on top of the CPU block points the wrong way on the revB). There are a very few AMD mobos that use the other s...

The more space inside a computer enclosure, the more airflow you need to move all that air in and then out of the computer. With a smaller enclosure, you dont need as much airflow to push it through at the same rate. So with a smaller case, you can use fewer and slower spinning fans. This seems so ...

Felger can you be more specific? I'm running SpeedFan and RMClock together for ages now. In XP and Vista 64 too. I have Speedfan 4.32. The RMClock install program is "...225_bin". My mobo is an Asrock NF4G-SATA2, which I use on both my #1 machine and its backup. On this equipment, they don't run to...

walle wrote:Felger, are you using the CU version or the aluminium ditto? and, what processor are you using it on?

Aluminum, and a Sempron64 3400+ socket 754. When stressing the CPU with 2 instances of BurnK7, it only requires 750RPM for the 92mm fan to keep the CPU at 60C. I don't run BurnK7 very often!
