Lord Kryo - Part 2: 24 CPU Coolers in Review

Lord Kryo Puts His Hands on 17 Coolers

Processors On The Rocks - Asetek's VapoChill

Rambler's Top100 Рейтинг@Mail.ru


Краткое содержание статьи: Gone are the days when a primitively designed CPU cooler with a minimal price tag would fit the bill for a PC system. We tested the latest generation of coolers, which perform their job much more efficiently. The bottom line - more complex construction, more detailed design, but also a heftier price tag.

Laboratory Tests Up Close & Personal - CPUs Maxed at 100%

We had already noticed during our last comparative tests that not many cooler models were a good compromise between the necessary cooling performance and an acceptable noise level. In fact, our readings showed that the majority of the coolers don't cool optimally. The testing platform consisted of an AMD reference board (AMD EVTS-BX-004) that was furnished with an AMD-750 chipset from the same manufacturer. All our readings were based on an AMD Athlon 1000 that worked with a 100 MHz front side bus. We used Windows 98 SE as an operating system platform. In order to keep CPU capacity use at 100% as much as possible, we ran the well-known program Seti, which processes data packets from the Internet. At the same time, we ran Flask Mpeg to create an MPEG-4 film and tested its playback. This ensured that the processor was constantly running at maximum capacity, which in turn ensured that heat flow was maximized.

Cooling Temperature

We carried out all the measurements in our Munich laboratory at an ambient temperature of exactly 24°C, two degrees higher than during the last test as a consequence of the warmer season. We calibrated the results in order to ensure comparability with the last measurements at 22°C.

Noise Level

We carried out our sound measurements in our newly conditioned sound measurement box, which simulates an almost completely soundproof environment.

Fan Speed

We measured the fan speeds of the new 23 coolers using a stroboscope. Each rotor was marked in order to facilitate the measuring of the speed.


The coolers were weighed using a precision weighing machine as is used in chemical laboratories to weigh materials.

История мейнфреймов: от Harvard Mark I до System z10 EC
Верите вы или нет, но были времена, когда компьютеры занимали целые комнаты. Сегодня вы работаете за небольшим персональным компьютером, но когда-то о таком можно было только мечтать. Предлагаем окунуться в историю и познакомиться с самыми знаковыми мейнфреймами за последние десятилетия.

Пятнадцать процессоров Intel x86, вошедших в историю
Компания Intel выпустила за годы существования немало процессоров x86, начиная с эпохи расцвета ПК, но не все из них оставили незабываемый след в истории. В нашей первой статье цикла мы рассмотрим пятнадцать наиболее любопытных и памятных процессоров Intel, от 8086 до Core 2 Duo.
