Re: Our Lapped CPU Heatsink Test Platform

Apart from that, I wonder if it might be an idea to polish the IHS and the base of the cooler against each other with a rubbing compound, after the initial lapping with sandpaper? Are you thinking of the way telescope makers grind their mirrors? If it works for them, why not cpu's/heatsinks? Intere...

Re: Our Lapped CPU Heatsink Test Platform

And alignment really matters. Actually, check out this review for a better explanation. The bit about the IHS and pictures that show it are from "Looking for an Explanation" and afterward. Thanks for this! I only had time to glimpse at the alignment pictures and conclusion, but the observations see...

Re: Our Lapped CPU Heatsink Test Platform

I described what I see in my OHS as a sag because the rim is raised, and the center is elevated compared with the surface between the center and the rim. Think lunar crater with a flattened mountain in the middle. And alignment really matters. Actually, check out this review for a better explanation...

Re: Our Lapped CPU Heatsink Test Platform

I have known about the IHS sag in my own i7 860 for years. I began to see the imprint of the IHS rim on the contact surface of every heatsink I tested. Since the heatsinks are copper under the nickle plating, they are fairly soft, so imprints always showed up. BTW--that is one way of detecting IHS s...

Re: Silverstone Fortress FT-03 and Raven 3

Heh. It's a compact thing, more a Fortrette than a Fortress.

As for the Raven 3 - quite creative, putting the psu up front and stashing the HD's behind the mb. Great concepts. But the bling . . .

I'm glad you contacted Antec. I have an NSK 4480-II with the same problem. I thought it was a bad MB, so I took the front connectors from another case and plugged that into the audio on my mb. No interference. And now you have paved the way for me and others to contact Antec for a fix. Bravo!

Check to see what comes in that Arctic cooling box. I got a 92mm PWM AC that has a wiring harness that allows you to control two or more fans with the WPM header. It even has a separate rpm wire so you can monitor the CPU fan's rpm along with the new fan's rpm.

Agree. Certainly wrong. Many fans click on Molex. Heck, I had fans clicking when I was using a wall brick as a power source. I read somewhere that it is the circuitry in the fan that clicks, and that if the manufacturer sets the switching at a high enough frequency we never hear it. Maybe true, mayb...

Fabulous review! Exactly what I wanted. I would have liked to see a Scythe Kaze Maru or Kaze Maru 2 tested as the middle fan. Like the Noctua, they have 120mm standard fan mounting holes. I have a P14 and three Kaze Marus - 500, 1200 and 1900. I am highly impressed with the KM's. When downvolted the...

At 440mm tall, this 17.3-inch case will fit under my shelf. That makes it a definite possible. At 207.40mm (I'll bet the paint varies more than 0.4mm) it is wider than the 200mm NZXT Beta Evo I am working on now. This should leave lots of room for both the bitumen and cable management. The side-moun...

Why bother selling off the case? If you like that form factor, it looks like a decent case.

As for fans, either get a pair of Gentle Typhoons or Noctua NF-S12B's - or go with a pair of Scythe Slipstreams.

But if you are going to change form factors, why bother buying new fans?

I have an Antec NSK 4480 II. It's nice enough. I put some inexpensive sound insulation on the main door, and it did reduce the noise a bit. The main thing is to get a quiet heatsink - or at least one you can't hear through the side grill. Don't put a fan in the front: it will vibrate the case withou...

Damping

Any stickies or articles on damping materials? I recently visited a high end music/electronics store and found something called "Quiet Zone," by Ixos, a self-sticking layer of heavy material designed to dampen vibrations. I've found some links on the net regarding damping materials, but nothing here...
