I have considered a Thermalright SI-120 with a 120mm Nexus fan on as an alternative to the Zalman. Will it be as cool as the Zalman and provide decent VRM cooling yet be more quiet? I used a Zalman CNPS 7000-Cu, first stock (with Fanmate), then modified with a quieter, isolated fan. I gained substa...

My Seagate 7200.7is only about 18 months old - pretty disgusting if it's already failing. I don't know the cause of the hum, but it happens when the drive is idle (which it is for all except about 2 minutes/day). The hum happens maybe once/week.

Here's a very inexpensive way (if you're in the US) to isolate the HDD's in the Sonata drive sleds. This isolation works great with a drive that is already pretty quiet (love my Samsung SP2004C!). However, the Seagate 7200.7 SATA drive (used for backups only) can occasionally hum irritatingly even ...

Maybe a Thermalright HR-05would be skinny enough to fit on your chipset next to the X1800XT? If so, it would benefit from the 92mm intake fans you're already using.

Check the base of your XP-90C for flatness. My XP-120 had a distinct "curl" around the edges that would have precluded good contact. I lapped it from the beginning so can't tell you about temp differences. But if the HS is getting warm (heatpipes and fins, right?), then it must be absorbing heat fro...

And as mentioned earlier, the Papst 4412 F/2GL (blue/silver label, made in Hungary) is a favorite in my system except for the initial cost. It comes closest to what teomilke thinks he wants: 55 CFM at 1600 rpm and claimed 26 dBA, which doesn't seem too far off compared to the Nexus and Yate Loon (me...

DO rpm's directly translate into airflow, does anyone know this? Roughly speaking, they are directly proportional. There was a thread in the last few months ago with pretty good data curves.

Do you know the Nexus 120 will be too low airflow? This is teomilke's thread, but I tried a Nexus 120 on the XP-120 cooling my less-hot Northwoods CPU, and found it let the CPU temp rise more under load then I was comfortable with.

I use the IR thermometer to measure the temperature of the exit air grill on the PSU, being sure to point it at an angle so that it is less likely to "see" a hot internal component. Seems reasonably consistent.

As ultrachrome suggested, an infrared thermometer works pretty well. They cover a wide range of prices, and the big variable is the viewing angle. They vary from 1:1 (one inch wide view at one inch distance; cheap) up to 50:1 or more (expensive). Here's a range from one manufacturer . I use the leas...

Definitely consider JimX's advice about the SI-120.

While I didn't have any fit problems with the XP-120, it is much quieter (with a Papst fan) then a fan-modified Zalman 7000; cooler, too, with the 3.0C Northwoods.
