Notes on different Quad G5 Cooling systems (dual and single pump)
" I had 3 different Quad G5s on the table in the last few days and it became obvious that Apple switched back to the Dual 2.5/2.7 liquid cooling system with just one pump. I heard reports about later Quads just reporting a single pump, so I looked into it (literally).

Not only does the system running on a newer Quad report just a single pump sensor, the difference is clearly audible. The twin-pump system emits a somewhat annoying, swelling hum, due to the addition and deletion of the noise from the two pumps, while the single-pump system just hums, no modulation or anything.

I didn't remove the CPU-block cover, but looking though the back fans of the later system you can clearly see the CPU-PSU heatsinks with the long heatpipes, just like in the old Dual-2.5.

I couldn't note any difference in cooling performance, both systems didn't have any problem to cool down the two CPUs.

The twin-pump systems had S/N around 55000, the younger, single-pump system I checked had a 60000-ish S/N.

I don't know why they switched. Maybe it was that annoying noise, maybe the single pump is simply cheaper, maybe there were other problems with the new system, who knows...

Saturn Cipher (Encrypted) ExDrive Review
" AMUG has just posted an article on the Addonics Saturn Cipher ExDrive. The model discussed in this review uses a SATA hard drive with 128-bit DES encryption. The Saturn Cipher ExDrive allows you to encrypt the entire drive in real time using a certified cryptographic engine inside an ASIC. This high quality DES hard drive encryption system does not tax the CPU or the hard drive. The article discusses configuration options, connections, compatibility, cooling, energy usage, performance and security issues.

More info from M-Audio on updated drivers, Enigma software for Intel CPU Macs
(in reply to a post in yesterday's news on M-Audio driver/firmware updates for some of their Firewire and USB devices)

" The M-Audio FireWire Family Driver is in beta. However, drivers for all other current M-Audio devices that can run on Intel Macintoshes are final versions. ( The complete list of M-Audio devices that have final drivers for Intel Macs is below:

USB devices
Black Box
Mobile Pre
Jam Lab
Audiophile USB
Fast Track
Fast Track Pro

MIDI devices/Keyboards
MIDISport 1x1
MIDISport 2x2
MIDISport 2x4
MIDISport 4x4
MIDISport 8x8
Oxygen 8

Other keyboards are class compliant in OS X (not requiring separate drivers). PCI devices are not listed, since there are no PCI Intel Macintoshes.

The Enigma software has also been released in an Intel Macintosh-compatible version.

MacBook Pro owner reports page updated
I've updated the MacBook Pro reports page with another owner mail on random shutdowns. A few others had mentioned this, one reader saying removing 3rd party ram helped on 2 samples with the problem - but this reader said that didn't solve the problem on his MacBook, which had only Apple installed ram. (One reader previously mentioned a possible suspect batch of motherboards, but only apple knows for sure.)

Intel Core Duo 2GHz iMac Mac World of Warcraft Performance
"WoW performance on iMac Intel Core Duo 20in, 2GHz, 2GB RAM, 256MB VRAM

Resolution 1680x1050
24 bit color 24 bit depth 2x multisample (AA)
Terrain distance maxed
Environment detail maxed
Texture detail maxed
Anisotropic filtering maxed
Terrain texture maxed
Spell effect detail maxed
All shader effects checked (only thing I can think of not enabled is trilinear filtering, not sure why I didn't turn this on....) Basically, everything is on full

- Indoor about 40 - 100 fps (in a "full" population realm at peak hour I'm sitting on 30+ fps when looking west across the bank- >auction house area, look at a wall and the framerate will max out at 100)

- Outdoor 25-50fps (normally with full screen glow unchecked)

- Mouse look is still extremely laggy, but this has been fixed on the PTR running version 1.10. Even with lower framerates the mouse movement is now very smooth on the test realm.

- Full screen glow is fine to enable in indoor instances but creates too much of a hit to framerates outdoors, ~ in the order of 10fps which is more noticable outdoors.

- I'll be going on my first MC/BWL runs on the new iMac this weekend, so I should be able to add some more info as to how it performs in the ulimate stress situations in 40 man raids (Raiding, for those who do not know is an area where Macs suffer far more than PCs, this appears to be an interface related issue that Blizzard has acknowledged)

- In conclusion, this is a fantastic machine, the first all-in-one that Apple has produced that really does have cutting edge technology and can easily run the latest games maxed out (as universal binaries) and older games not yet recompiled run just fine on middling settings.

I've added this to the page of Mac WoW performance which has other Intel CPU and PowerPC Mac user's notes on FPS rates seen in play.

How's your Alum Powerbook Finish Holding Up?
(Update - as of 4PM Eastern time Friday I had 11 replies to this post - several noting they also had some finish wear or black spots/pitting, etc., although some said theirs still looks great, especially with regular care/cleaning.)

" i was wondering if any other owners of the aluminum PB have issues of losing paint in the small area between the track pad and keyboard. My PB is 1.67ghz 15", I have had it since June 2005. I can send a pic if you would like.
-Aaron "

I use an older 17in AL Powerbook G4 daily (1.33GHz, bought light used) for the last 2 years but always use a mouse with it - so far the finish looks fine - not sure if it's painted or some sort of clear anodize, but other than some stains at times and a few scratches - it still looks good so far. (The Ti Powerbooks however often had finish/paint problems - I had one where the paint on the outer trim ring cracked and flaked off and some owners of them years ago posted pictures of paint wearing through, etc.)
If any AL Powerbook users have had finish problems let me know.

If you've added a IDE, SCSI, Firewire or USB hard drive, CDRW, tape drive, etc. make sure you add a report to the database. (If you post an updated entry - make sure you use the same name, etc. as you did before so I can find your past entry. Thanks.)
(Incomplete entries are deleted. Do not post questions in the database, it's for drive reports not questions on what drive to buy - for that try searching the database for reports from owners of your mac model on the drive type/brand/interface, etc. you're interested in.)
