Owner Feedback on Maxtor 7200 RPM Drive Temperatures
Published: 2/28/2000

I noted both the 27GB and 40GB Maxtor DiamondMax Plus drives seem to run warmer than other IDE drives I've tested in the past. (Installed in the B&W G3 and 9600 cases or a Firewire/IDE case with extended use there were never any problems, and in the new Mac case design the drives seemed as cool as the OEM drive.).

There have been some reader comments in the past (a few) that Beige G3 desktop systems seemed to run higher CPU temperatures after adding a Maxtor 7200 RPM drive. The weekend of 2/26/2000, a post in my G4/Upgrades forum (see below) helped clear up the issue with actual mac owner reports.

The original forum post that started this thread:

"Staples Says Maxtor 40 gig Runs Hot???
Chuck Hornback -- Sunday, 27 February 2000, at 2:12 a.m.

Went by the local Staples in Anaheim Ca to get the new Maxtor 40 gig/7200rpm/IDE. The salesman said he installed one in his WinDoZe box and it overheated his machine. He installed an addition fan and also noted to keep it away from other drives. Since I have a G4 400mhz(Yikes) Apple says to mount addition IDE above the factory installed drive (10 gig Fireball). I know that Mike B. noted that the drive ran a little warm but nothing like the Staple guy described. What do you think, anybody else install one of these yet. I'm not really confident in the Salesman advice, but I delyed my purchase for now. Any advice would be greatly appreciated. "

I've been running my G4 with the system drive, the Maxtor 40, 2 ProTools PCI cards, and an Aurora Fuse video card for 4 days without a hitch. The G4 runs about 10-12 hours a day.

I was anxious about it at first, but it seems to be OK. I've ordered a second Maxtor to mount above the CDrom - nothing like living life on the edge! Anyway, I'll be curious to see if it causes any problems. "

I have a Maxtor 7200rpm 40gb drive in a beige G3 mini-tower. I took the original Quantum 9gb SCSI drive and put it in the drive bay below my DVD-ROM, and put the new Maxtor where the SCSI was in the had drive bracket above the power supply. I have had a thermometer (the indoor/outdoor digital ones with a wire for outside temp) taped to the drive for about a half hour, and It peaked at 91 degreed Fahrenheit. Currently at 90.9. My current room temp is 73.8, and I have no additional fans in my G3.

My quantum SCSI on the other hand runs much hotter, feels hotter to the touch, especially since it is below the CD drive and there is no lace for the heat to go. I will post temps on the quantum in about a half hour, since I have had it spun down, it will need time to warm up. Overall, heat should not be an issue in a beige g3, even if you decide to place the Maxtor right below the DVD/CD-ROM. For best results though, I suggest you mount the 40gb in the drive bracket above the power supply, then put the stock hard disk below the CD. Personally, though, I would remove the stock HD all together and just replace the stock drive with the Maxtor.

Mike has an article on replacing the beige g3 stock HD, take a look at that. sorry no link, maybe mike will post one, but check out: you can find a link there. [The Beige G3 IDE drive upgrade article is at and also linked in the storage topics page and the how-to area of the FAQ -Mike.

if you need more info, just post another response!

Chad later wrote with temperatures on his stock SCSI drive:

My Quantum SCSI drive temp:
101.6 degrees F
The maxtor runs nearly 10 degrees cooler than the stock scsi drive that came in my computer, so the Maxtor is fine heat wise. The scsi is probably a little warmer than usual since its right below my DVD-ROM, rather than in the bracket above the powersupply, so that could be causing a little extra heat, but everything is fine.

I have a beige G3 233 upgraded via XLR8 Mach G3z 466 MHz overclocked to 500 MHz, Maxtor 27.2 GB 7200 RPM hard drive, the original 4 MB oem hard drive (in the bay above the ZIP bay), and a VooDoo3 2000 card all in my machine generating heat. According to Gauge Pro, I normally run at around 96F "

This Beige G3 owner reports he's running 3 Maxtor drives with no temperature problems:

I'm running three hard drives in my biege Rev 1 G3 desktop. I have the Maxtor 40G (7200RPM) and a Maxtor 17G (5400RPM) in the upper drive bays.. I also have a Western Digital 13G (5400RPM) in the lower hard drive bay. The Maxtors are hooked up to a ProMax ATA/33 controller card and the Western Digital is on one of the onboard IDE controllers. Eventually I may do a Master/Slave setup with the Maxtor 17 and the WD 13 utilizing one of the controllers on the ProMax card to improve performance of the WD drive.

The temp of my processor remains the same at 40-44c as reported by XLR8 MACh Speed Control. This is the same temp Speed Control was reporting before the Maxtor 40 installation. I'm assuming if the inside of my machine were getting too hot, it would reflect in processor temps. The only time the temperature climbs to 44c is if I'm playing Mp3s or playing a wicked game of Unreal Tourny. I also have a PCI Voodoo 3/2000 overclocked using the 3000 ROM. The 433 ZIF i was running prior to this 500Mhz ZIF (overclocked 450 Aluminum) was running at 56c-60c...just a bit too hot for comfort.

As an aside for any Biege G3 owners, ATTO Tools reports huge improvements with the Maxtor drives after hooking them up to the ProMax card. The onboard IDE controllers on the biege G3's are really dated and slow! "

A reader has more questions for Chad:

"Thanks Chad...
Beyond -- Sunday, 27 February 2000, at 6:19 p.m.

for your detail report on the temp issues. But did you say your stock drive is SCSI? Mine is an ATA, and is mounted right above the power supply (BTW I have a MiniTower). I'm planning to replace the stock 6GB drive with an Maxtor/40GB. If running at 91F, I worry it might burn up ;^)

Also, I'm planning on buying an ATA controller for it, either a Acard/ATA66 or the Promax/ATA33. I already have a USB card and an ATI Rage Orion in my machine... With too many upgraded components, I think I need another fan for it. My room has no window and is warm most of the time (~75F)...

Anyone knows what fan will fit and where to hook up the power? "

I don't think you really need to worry about a fan, and as of an ata/33 or ata/66 card, i wouldnt really mess with it. Having a hard disk connected to pci slots sucks alot of my cpu. My original scsi drive (uses pci scsi contorller card) and my new maxtor 40gb performed about the same in atto tools benchmarks (the maxtor a little faster), but with the ide drive i thought i bought a processor upgrade, everything was way more zippy when the hard disk was in use, and video updates seemed to suffer with my scsi drive when in use also. This would not be a problem if video and pci were on a different bus, but video and pci expansion are onthe same bus on Beige G3 machines. Differend story on B&W G3s and G3s. I suggest just using the onboard ide in the Beige G3, although i wish I do have ata/33, and pci card really does not seem to be a good way to go.

A G4 owner reports on temperature and noise levels:

Picked up the Maxto 40 Gig and put it in my G4, 450 yesterday. Paid just $249 at Staples by showing them a copy of the price on CompUSA's webpage. They matched the price. Anyway it's sitting on top of the original drive and hence sitting just below the fan. Runs very very cool. And very quiet. Did some Final Cut Pro with it and runs great, no drops. What a deal!!! "

The above should put the worries over temperature to rest.
