Slower Fans for E6300 and E6400 Series
The thermal dissipation loss is virtually proportional to the core frequency. Simply put, the higher the CPU frequency, the higher the resulting thermal power loss. The reverse is true as well though, meaning that CPUs with lower clock speeds require less elaborate cooling.
This is why Intel ships its Core 2 models of the E6300 and E6400 lines with a modified box cooler. Although it shares the same design using a copper core surrounded by aluminium cooling fins with its high-performance siblings, it sports a different fan. Its motor is only a 2.4 Watt model, compared to the 4.7 Watt version on the more powerful coolers.
As a result of the less powerful fan motor, the fan speeds are also lower. This model reaches a maximum speed of 1740 rpm, while its idle speed is 820 rpm.
Such a pared-down model is no longer able to cool our quad-core processor. Under full load, the CPU temperature rises to 92.8°C, which is just below the throttling threshold. On the plus side, the cooler never gets louder than 40 dB(A) thanks to its slower fan, by no means loud enough to become annoying.
| CPU | 100% load | idle |
|---|---|---|
| Temperature PWM | 92.8 °C | 50.5 °C |
| Noise | 40.2 dB(A) | 39.2 dB(A) |
| Fan speedl | 1740 rpm | 820 rpm |
| Weight | 436 grams | |
| Intel socket | 775 |

I thought hes got to be kidding then I looked down page 7 and lmao. Its a whole paragraph in German.
Question to the article creator; Is this the last in the cpu cooler charts 2008?
lol @ the German
How come the Arctic Freezer Pro 7 was not covered in this series? It's quite a popular cooler and I would be interested in seeing how it compares (as that's what I'm using).
that german has got to be the best typo ever. you tested stock coolers but didnt test an arctic cooler 7? the articles all say that arctic cooling is represented in this test but I fail to see where?das ist nicht los!!

My apologies.
Thanks for the heads-up...
We translators also have our off days. Consider me awake now
I think box coolers have to compromise between price and performance, so it's pretty much a foregone conclusion as to one's expectation.

However I have had some pleasant surprises; a lot of the boxed AMD processors I have bought (S393 and AM2 in medium speed ranges), have had pretty good coolers. Granted they run on cool processors so they aren't really pushed to the limit, but they do perform excellent: low-noise, good cooling, good MTBF, and decent overclocking results.
Something else I've also noticed - price doesn't buy a good cooler. Some of the more expensive devices are very noisy, bulky and (as I did), you end up wondering where you went wrong. I've bought expensive coolers with copper fins and small fans and had to remove them..they're simply too noisy. I replaced them with devices from Cooler Master etc (some of which were the cheapest I could find i.e. bargain basement), and have had no problems whatsoever. I don't work for Cooler Master but credit is where credit's due - they do their job and they generally do it well.
I think you can get a good boxed cooler, but it's the luck of the draw depending on the platform and particular processor model. If you have an overtly noisy cooler you can always alter your BIOS settings to only spin the fan up when a critical point is reached. Most CPU's just run idle a lot of the time so there's no point suffering or wasting electricity.
p.s. Please..please..manufacturers, you know the LED fans? Please put a switch on them will ya?
