Innovibe is aluminum blocks (not rubber) that attach to the drive sides, and rubber standoffs where the screws go in. The aluminum blocks are a good idea to assist in cooling the drive. But the rubber standoffs make it difficult to install. As you squeeze an Innovibe equipped drive into a 5.25 inch ...

spudston, UPS charges the 1 pound rate to ship anything under 1 pound. This is why the isolators are "ridiculous" to ship. Also, they charge the same to ship something worth 1 cent as they do to ship something worth $100.00. If you don't need a tracked shipment with guaranteed delivery then we are h...

You can buy Panaflos with both 3 pin and 4 pin tails. There is no standard. But most commonly they come with a 2 pin connector that will fit on a 3 pin connector when one of the polarity tabs is trimmed off. In my testing a Zalman 92 mm fan in silent mode (5 v) is 10 db quieter then a Panaflo 80 mm ...

I see you are right that there will be an 8 meg made in the future. But the drive in that review is a 2 meg. You can see from the model number (ST3120023A) in the photos and text that it is the 2 meg version.

pingu666,
You are right about the specs of the Barracuda V. I think the author of that review was confused. There is no 8 meg ata version.

Many other points in the post are right-on, but this one skipped a beat. Total heat in = Total heat out. The smaller heatsink will get hotter because it's shedding the same watts in less area. The hotter heatsink might fiddle the electrical performance a wee bit, albeit not much. It might sink a bi...

Mike, There are a couple difficulties with this methodology. To illustrate the let me present two thought experiments using air temp as the test indicator. For the first experiment assume two otherwise identical PSUs, one with a high CFM fan and one low CFM fan. The PSU with the higher CFM will have...

It was a 150-watt ATX PSU to power a computer system. It was open frame because of a special requirement to attach its heat producing bits to the frame of the case. I've not had a fire in a normal enclosed PSU (yet). The case of a normal PSU would have been enough to contain the fire spread. But not...

Maybe I am just unlucky with computerz (I have always believed this to be true) but let me assure you that PSUs can in fact catch fire.

I don't recommend the 60 mm Panaflos. It is tempting to think that since the 80 mm Panaflo is such a great fan that the 60 mm must be great also, but that is far from the case. It exhibits very bad vibration. These fans are unpleasant in free air but try them coupled to a case and they are downright...

If cool is more important then quiet then either of the PSUs you mention should suit you fine. Having said that, I think you are in the wrong place.

We don't carry it right now primarily because the design doesn't seem very compelling to me. It appears to be just a flat piece of copper attached to a small Verax fan. The smaller Verax fans are much quieter then normal tubeaxial fans, but I’d still prefer to use no fan at all. I'm hoping that the ...

The connector on a Panaflo that sells for 2-3 dollars will be a 2 pin Molex KK style. These connectors are like those that are on a motherboard, but they have 2 pins instead of 3. You can clip off one of the polarity labs and a 2 pin will fit on a 3 pin. The $2 Panaflo phenomenon is as a result of a...

It is very tempting to "hot" plug your fans when tinkering with your system. I do it all the time. As Mike says, it is no different then flipping a switch, but perhaps flipping a switch is not completely safe either. On one occasion I damaged a motherboard from hot plugging a fan, and as a result AL...

Chief, You are correct that there is no possible thermal benefit from a copper heat spreader when used with a carefully attached copper heat sink, and in fact there is an increased thermal resistance because of the added thermal interface layer.

In addition to that, the boards can automatically scale back the processor speed to reduce heat, and consequently fan s...

Mike, <br>The boards are very clean looking. There are unusually few circuit traces on the surface of the board, which must mean most of it is located on the inside layers. The P4 board has an optional reinforcing metal bracket that attaches on the backside behind the CPU. I presume this is an attem...
