I need a way to supercool a laptop, STAT! Answered

Well I'm getting tired again of my mac being extremely sluggish most of the time (the hd is pretty fragmented, too lazy to get my boot disk takes a few hours to defrag). A lot of the "sluggishness" is due in part to the rather extremely hot 1.2ghz ppc processor. I've tried putting xbox heatsinks on it (like seen in my instructable, search that shit) and I even made an addition of putting a fan ontop, but at the most I might have seen a reduction of 5C, but under load the fan made no difference. I know the internal fan can cool it down from like 78C (it gets hotter playing halo) to a nice 50C in a hurry at full speed. I haven't touched it though (wanting to hardwire it badly) because it has like 9 different wires for whatever reason (ground, positive and your sensor readout is all you should need right??). Anyone have at least some half assed idea of what I could throw together in a jumble? And yes, I've thought of using a peice of plexi-glass and cutting holes in it for computer fans and making a souped up cooling pad, but I don't have the fans.


Do you have 1 or 2 Hard drives? Having run Mac's myself for audio production, if you add a second HD and run that for temp files for your programs you will take the load off the processor and free up memory as well. It will run smoother, faster and stay cooler as well. In a pinch you can use an Ipod as an outboard HD. You can even use a Usb thumb drive, but those will get really hot and not as optimal of a performance. Playing Halo you might even fry it out...BTW....all this works for PC's as well. Have you tried Norton Disk Doctor for de-fragging? In my experience's, it will defrag a 40gig drive in about 20 minutes. Well worth the purchase! I work with MAC and PC so I am very comfortable with both. Not to sound like a jerk, my only problem with MAC is the lack of backwards and forward compatibility....other than that I don't see either of them as better than the other. Kinda like comparing a Black Lab to a Yellow Lab...they are both Dogs, and they will fetch a stick if you throw it....Remember...its not the size of the dog in a fight, but the size of the fight in a dog that counts.

Norton Disk Doctor hasn't been available for Mac since OS X 10.2. Don't ever use it with a newer OS! If you must defrag, and again I don't find it necessary, Use Techtool Pro, booted from the CD. Backward and forward compatibility? You mean from OS 9 and before and OS X?

oopS....Sorry....I mis-read that...I thought he was running OS9. As far as compatibility, yes. Thats what I mean. I just dumped a G3 that was in perfect working order because I couldn't get a replacement CD Rom or burner for it. The burner I had in that studio would only recognize 650mb CD's anyway, which have become impossible to find. That whole audio workstation set up was built for $27,000 (including the Pro Tools and Master list software which are keyed to that machine only) and lasted less than 6 years before becoming obsolete. I have studios built with G-4's that are also quickly becoming extinct. On the flip side....I have a Windows 98 machine set up in a studio that I built in 98 and it is still running strong 9 years later. It was built for $3000. I have replaced and upgraded where needed and its still going strong. Backward and Forward compatibility may not mean much to you, but when clients do a capital expenditure to build a recording studio and life expectancy is less than its depreciation value...they get a little pissed. Thats why most studio builds I do now, I recommend PC over Mac. Its cheaper and more cost effective. Lex

G3 Desktop? You could have used any Pioneer drive. They work fine. Everything produced today is still fully compatible with your G4. Other than Intel specific utilities, I know of nothing that won't work on a G4. The keys for Pro Tools, Master list and (my preference) Logic Pro use USB dongles and can be easily moved to a newer machine. I had a client that used a Mac II+ for music composition and it worked well before she finally upgraded to a 9500. Her next upgrade was to a G5 DP. All three transitions worked smoothly. Of course, as new and better software became available, they were purchased as used. The same MIDI equipment that she used with the Mac II+ is still in use, other than the MIDI interface that was upgraded to a USB device. Yes... If you're resistant to upgrading, eventually the old equipment become more of a detriment than benefit. I'm sure you have no P2 systems still in use.

The Pioneers say they are compatible, but only as far back as OS9. The G3 is toast. When I built those that was before dongles. It was a Diskette and its a one time use that keys to that machine only. I'm not talking about the Pro Tools you buy at the consumer level which allows multiple licenses. As for the G4's....its only a matter of time. MIDI hasnt changed much in 15 years and isn't in the same realm as recording and mixing a band and producing an album. Scary thing is most Consumer level audio and Video programs now are almost as good as the pro stuff at a tenth of the cost. You just cant get all the cool plug-ins, but the plug ins you do get are still pretty sweet. BTW, you can pick up Pro Tools M software for $200, LE bundle for $2000 and the pro bundle for about $13,000(includes core cards). Big difference in cost, big difference in performance. As far as DVCPRO P2's go they rock! Pentium II's....well those are now Door Stops....

Well... That pre-OS X G3 is as old, if not older than a Pentium II. While obsolete, those OS 9 programs you're using still work as good as they did when new.

The external drives were the problem. The G3 was running fine. It was a 350...It was just after Pentium IV came out and right before the G4's hit the market. G4's are running perfect and they are 350's as well. But I foresee the day when they become obsolete.

I only have the internal 60gig hd, I do have an external usb controller, and a 6gig hd, but it's too slow (prolly 33mb/s). I do have a xbox 10 giger hd, but I can't unlock it, although it would probably do the trick. And norton utilities probably only defragment user files, which are all that are accessable when you're defragmenting a mounted partition. The software I use is idefrag on a boot disk and it defragments my metadata, b-tree catologues, the whole deal, but it does take a while.

Unless you're running OS 9 or before, fragmentation shouldn't be a real problem. As to your mods, as a said in your Instructable, I don't believe them to be better that the original cooling system. Of course the processor in a notebook tends to run a bit hotter than those in a desktop. That's normal. They're actually designed that way. The cooling system is also normally designed to disburse that heat over as wide an area as possible. Cooling the processor more will not make it run faster. All it would do is prevent the processor from erroring out because it got too hot. Does it?

Fragmentation is an issue. The HFS+ filesystem isn't all it's "cracked up to be" and isn't invincible to fragmentation, and after using torrents for how long on it, my disk defragg software is showing that the disk is actually rather fragmented. And the instructable I made wasn't ment to replace the internal heatsink design, but to aid it. And I'm not exactly sure where you're coming from with "they run hotter than desktop pc's so it's fine cuz that's normal". It's not nessasarily good for the processor, and if you're about to tell me that my mac running at 80C literally is "normal" you're crazy, it should only be around 55C under load.

It's not the filesystem, I'm refering too. OS 10 does its own background maintenance. 10.3 to present does it even better, unless your drive is near full. I was saying that notebook computers use higher temperature processors that desktop computers. Some of the early release iBook G4s did have a flaw in manufacture, where too much compound was used, and they did overheat. The cure was to remove the majority of the compound, but leave the design intact. Placing heatsinks on top isn't going to change much at all. 80C is a little high under normal load and may have merited a repair from Apple. My Intel Macbook Pro runs under normal load about 65C up to around 75C with a medium load. It's high temperature under full load is supposed to be around 86C. My older Powerbook G4 ran normally around 70C.

Where are you getting your information??? The background deframentation (The hfs file system is bult to reduce fragmentation, it's not part of os10 that does it, it's the file system.) is really only to "reduce" the fragmentation that occurs on all computers, it doesn't completely "Rid" of it. Also too, I haven't seen one single ibook g4 that used thermal paste, they all were shipped from the foxcon factory with thermal pads. I do remember though that this machine did used to run cooler, like 40-50C even under load.

My advice is to get a windows pc, meaning no mac. Yuck!

Sigh,..I have a thinkpad r51 sitting right here, I'm good thx. Apparently people can't appreciate good hardware design.

Obviously, acer73; Computers aren't the only thing you have no clue about.
