CoolJag 661C P4 & V558A XP Heatsink Reviews
Cooling/CPU Cooling by SidneyWong @ 2004-08-25
Today, we are looking into the two most commonly used coolers; 661C for socket 478 Pentium 4 and V558A for socket 462 AXP provided by CoolJag.
Installation & Testing
P4 Test setup:
The case used was a Lian-Li PC60 with Aquarium Panel ;) and following fan configuration:
2x 80mm intake ~2200 rpm
1x 80mm exhaust ~2600 rpm
1x 80mm top-blower ~2,000 rpm
Arctic Silver Ceramique was used for this test and the ambient temp was 25-26 °C
Let’s go to find out how it performs. The test rig was equipped with Arctic Cooling 4 Pro which I like a lot, and its performance is very similar to Intel Stock copper based without the noise. With “Prescott application” label on the box, I went ahead without changing the over-clocked setting. Two minutes into Sandra Burn-In, I had to turn the system off as MBM5 was showing 68C. I was dazzled for few seconds; this thing had got to be better than the all aluminum 4 Pro. This is what I found when I removed the Heatsink.
The Heatsink is not making good contact with the processor. I remounted it and made sure everything was done right. The same happened. If you look at the Heatsink base you would notice the entire base surface is level; notice the “smeared “marking on the lower right hand corner. This is the problem; the Heatsink is not making full contact because ……
The retention bracket hold down pins (in white) located at the four corners are protruding upward rather than recessed or flushed preventing the base to make full contact with the processor.
By grinding off the corners of the base would allow full contact. I called CoolJag and let them know the problem; I was then told that they did not encounter this problem with Intel and MSI boards. Anyway with this out of the way, I proceeded to what I supposed to do two hours before.
After boot-up, the CPU fan is turning at a lazy 1,500 RPM confirmed by both SF-609 Fan Master and MBM5. Sandra Burn-in time, after 4 loops the system locked up, CPU temp hit 68C again; the fan reached 2,400 RPM before the hiccup. 70mm fan does not push much air flow at 2,400 rpm, the fan speed did not increase much might well be due to my good case ventilation. I decided to short out the temp sensor to make the fan run at full speed. With the very short leads, I finally managed to jump the two leads 30 minutes later. This has become the longest Heatsink test insofar.
At 6,000 rpm the 66IC doesn’t sound as bad as the AVC Sunflower which uses similar 70x70x15 mm fan. However, it is loud in today’s standard – 58 dBA 18” away from my digital sound meter comparing to 42 dBA generated by Arctic Cooling 4 Pro.
For those who have had owned several P4 would know the motherboard/BIOS reporting temperature varies drastically. At present my two IC7 boards differ in CPU temp report exceeding 10C using identical setup. And, the temp from my two Asus boards are another few C’s lower than the lowest reporting IC7. The funny part is that my two Asus boards have temp reporting within 2-3C from the SF-609. I let you figure it out. With this kind of temp readings, I am including external temp probe using SF-609 as reference.
I’d say CoolJag 66IC beats the Super Silent 4 Pro with its full copper sink slightly but lost in term of sound level big time.
