Z820 - Added Liquid Cooling Option

Hi,
I upgraded my Z820 with the liquid cooled CPU heatsinks.
Apparently the 'fan cooling profile' is based on the hardware configuration, do I need to do anything else or will the system detect the changes at boot time?
Reset the CMOS for example?
Thanks,
Rob

Hi,
It's your machine, out of warranty, you can do what ever you like, you can remove the whole case and blow cool air to the machine, you can drill dozen holes to get better air flow, you can pour chilled water thru all corners of the machine ..... and this will reduce 5 or 10 degrees. The question: do you want to do that ?
Regards.

Z420 ventilation / fan / liquid cooling

hi,
I have z420 (E5-1620)
Serial Number: [Personal Information Removed]
Product No. WM434EA#AK6
this thing is loud as hell since day one. I'm not a heavy user, but I do work with grapchics (photoshop mostly).
had to add 16Gb RAM, ssd for OS, 3 secondary hdd's for storing, hd 7870 asus, 2x hp monitors..
anyways, I'm looking for ways to make it work more silent. and heard about "liquid cooling" available for z420.
1 - is it worth getting? will it make it work more silent (while in normal workload / idle mode)?
2 - would it be possible to get myself a different brand of liquid cooling suitable for this mashine? point out some pls.
for instance, these http://www.corsair.com/us/cpu-cooling-kits/hydro-series-water-cooling-cpu-cooler.html compatible?
3 - I noticed my model came without this part/fan in red cicrcle:
what product model/no. is it? would it help me with my issue?
more info about fans on z420:
Cooling Solutions Air cooled forced convection, liquid cooling (optional)
Power Supply Fans 92 mm x 92 mm x 25 mm 4-wire (non-serviceable)
CPU Heatsink Fan 92 x 25 mm 5-wire PWM
Chassis Fan 92 mm x 92mm x 25 mm 4-wire PWM
Memory Heatsink Fan Yes, rear memory
any help would be realy realy much appreciated. I work with this thing EVERY DAY. I need to make some changes or start looking for other solution/PC

I have not tried the liquid cooling as of yet, http://homepage.mac.com/steve.smedley/Personal9.html, (saw the same kits at Comp USA), but did settle for the verax fan kit.
I recently upgraded my MDD FW800 1GHz single cpu (133MHz bus) to a dual 1GHz using a new module meant for an Xserve with with the same bus speed.
It essentially turned my reasonably quiet Mac into a wind tunnel with temps running at 134˚F to 136˚F running idle, and as much as 138˚F under a full load.
The Verax kit has lowered my temps, right now running at 127˚F with just Safari open, and running as high as 129˚ to 130˚F under a heavy load, but not as noisey. The 120mm fan now just runs at a lower constant speed which is alot quieter, my power supply fans are another story and they are next on the list, right now they are making the most noise everything else is a much quieter whoosh of air.
The Verax kit is quiet, considering I have now have 5 fans in my Mac and the power supply fans are now my only noise makers, a constant steady irritating noise at that.
Just a note about the Verax fan kit, they include a 80mm fan to replace the 120mm, I opted not to use it because I wanted more intake for inside the case, the one they sent looks like a piece of crap, and I know the cfm had to be much lower than the 120mm.

Z800 secondary cooling duct part number for water cool option.

Hi
I need the part number dor the secondary cooling duct on a z800 it mounts to the main airflow cover using the water cooling option. It can be seen in this pdf on page 5 bottom right corner. You can see it attached.
http://h20331.www2.hp.com/Hpsub/downloads/Increasing-thermal-efficiency-with-liquid-cooling.pdf
If you do not know the part number a serial number of a pc with the item in question would also work.
thanks

HT1473 I got my MAC PRO installed with iOS lion and since then i'm unable to add music on my iTunes and i tried adding to library option but still it copies and at the end it stays empty, doesn't even open new songs on it. any suggestions ?

hey,
I've rebooted my mac before installing new ios lion, so after everything was done i copied my data back to my mac book pro, then simple clicked on adding to library option in itune and it only synced half of the track and rest simply didnt copy, i thought maybe some error occured and i tryed the same procedure again but its not adding more tracks in it. and i just notice when ever i try play a new song through my data it does not open in itune these are the same tracks and songs i been listening to since ages on different note books and pods..
Help me i've tryed everything but nathing seems to be working. and my itune is uptodated =S

Use the trackpad to scroll, thats what it was designed for. The scroll bars automatically disappear when not being used and will appear if you scroll up or down using the trackpad.
This is a user-to-user forum and most people will post on here if they have problems. You very rarely get people posting to say there update went smooth. The fact is the vast majority of Mountain Lion users will not be experiencing any major problems with the OS, or maybe with apps which are not compatible, but thats hardly Apple's fault if developers don't update their apps.

Process for adding a boolean option to the web service API

Hey guys,
Here's a little background:
I'm currently working on adding an optional "strict" mode to some of the unmarshalling functions in SchemaMarshaller that will throw exceptions when receiving bad data for certain fields, and also improving the date handling while I'm at it (I want null instead of mangled dates when receiving bad data when strict mode is off).
This is for my benefit at the moment as I'm tired of spending time debugging Flex code when XFire and Oracle are spitting out rubbish (like empty xsd:DateTime nodes, DateTimes in xsd:Date nodes, etc) - but I'm sure other people would like to use it too while we don't have a response validator, so I'd like to do it in a way that I can submit as a feature request (with patch) on Jira.
My questions are about the procedure for stuff like this- where should this option be made public in the API, and who would I talk to about it? Or would it be best for it to always be strict? - That's how I'd like it :) Perhaps it should just log errors when it encounters bad data?
This is the first thing I'd like to "add" to the SDK rather than a simple bug-fix, so I just want to do things in a kosher manner. Sorry if I come across like a total noob :)
Cheers,
-Josh

Hey Josh, I'm swamped at the moment but appreciate your interest and your contributions to Flex and WebServices thus far. I'll try and get some time to look into your specific request and what you're hoping to do at the code level, but to answer your question about test cases, you should consider the NIST testsuite for XML Schema datatypes. BlazeDS has historically maintained the WebService implementation, so it appears their test case for NIST based schema tests starts out here (and refers to many data type test cases in the /nist subdirectory). http://opensource.adobe.com/svn/opensource/blazeds/branches/3.0.x/qa/app s/qa-regress/testsuites/flexunit/src/tests/flexunit/xml/NISTXMLSchemaTes t.as Pete ________________________________ From: [email protected] [mailto:[email protected]] On Behalf Of Josh McDonald Sent: Tuesday, July 08, 2008 8:21 PM To: [email protected] Subject: Re: Process for adding a boolean option to the web service API A new message was posted by Josh McDonald in Developers -- Process for adding a boolean option to the web service API Yeah I knew it'd have to be somewhere outside of SchemaMarshaller, as it's [ExcludeClass] anyway so end users don't see it, nor is it documented in the api docs.

I'd then also add an option to the WebService class itself, and basically in the Operation it should see if it has its own value set and if not check the value on the WebService. We do this for a couple of other flags too I think. End users in general wouldn't look at any classes other than the WebService and maybe the Operation classes, so asking them to set options on the schema classes themselves probably wouldn't work.

G5 liquid cooled needs a new logicboard...HELP

My fathers G5 was tested at the apple store.
they said it needs a new logicboard.
CAn I do this?
it has dual 2.5's liquid cooled.
Do I need to make sure the new logicboard is a match?
will others work?
Replacing logicboards is new to me.
Any advice or info would be greatly appreciated.
Thanks

Hi ksgraphite-
Greetings and welcome to the Apple boards.
Replacing the logic board will be a very involved job and there is much that could go wrong. If you are up to the task I would suggest checking with these folks: MAC-PRO

Liquid cooled G5 issue

I have a dual 2.5ghz G5 Power Mac which recently started to make a horrid noise which I think was coming from the pump for the liquid cooling system. There was a sort of liquid sloshing sound and a whine like you get when your car windscreen cleaning system has run out of fluid.
I checked for coolant leaks and found nothing. I took the machine in to an Apple Service Center and they have now told me that the CPUs need replacing at a cost of £700. I don't trust this diagnosis. The machine ran fine, albeit at a higher temperature than normal.
I'm not interested in paying half what I paid for the machine brand new just to replace CPUs, particularly for a machine that is discontinued.
Can anyone offer me some suggestions as to what I can do about the machine?

Took primary tower in to apple today with coolant dripping from rear. . .
we run two G4 1ghz laptops, two G4 towers 500mhz and 466mhz. . newest computer of bunch craps out on me with a coolant leak?
APPLE PowerMac G5 Coolant Leaks World database report
http://www.fusina.net/G5coolantleaks/index-stats.php
Only 3 models were made with liquid coolant?
was quoted $625 for processor replacement $85 for hardware repair level-1 $710 total?
seems I made a mistake in purchasing liquid cooled mac. . .
the dual 2.5ghz accounts for 78% of failed coolant systems, check database link above, maybe apple could provide database with access for users to keep track of worst mac systems built. . .
there was another thread that apple decided to put into the archives at http://discussions.apple.com/thread.jspa?threadID=957435&tstart=0
why does apple not have a uniform repair policy with these failed machines? Why do I need to speak with a manager and pursue all these avenues to deal with what seems to me a faulty piece of machinery that I have built system of peripherals around?
Manager at apple store has agreed to wave $100 diagnostic fee and to cover half cost of $710 repair bill. Not feeling great with the idea of paying $355+ in repairs for a computer that will probably start leaking once I put it back into high gear crunching data. . .
Others have had apple estimates of $1100 or even $2500 plus in overseas markets. . .
Could apple remove liquid cooling system, thereby eliminating future leaks/catastrophe's?
Plan on making calls to APPLE to see if repair can be cleared regardless of out of warranty status. Pains me to have bought liquid cooled computer knowing that Apple removed cooling system in future models. . .
Oh yeah found in the G5 online manual they say. . .
Liquid Cooling System, Some Power Mac G5 models use a liquid cooling system to manage the temperature in the computer. The liquid cooling system is sealed and is designed to be opened only by an Apple Authorized Service Provider (AASP). · Warning: Do not attempt to open or service the liquid cooling system. Opening the liquid cooling system may damage your equipment, and such damage may not be covered by the limited warranty on your computer.
· Warning: Always operate your computer in an upright position. In the unlikely event that coolant leaks in or from your computer, disconnect all electrical power to the computer and do not restart it. Contact an Apple Authorized Service Provider or Apple for information about servicing your computer. After disconnecting electrical power, you can clean up coolant using an absorbent cloth. Avoid inhaling or direct contact with skin. Coolant may cause minor skin irritation. If coolant contacts skin, wash well with soap and water. If coolant contacts eyes, rinse thoroughly with water. Dispose of all clean-up materials in accordance with your local environmental laws, regulations, and guidelines. Coolant may be harmful if swallowed. Material Safety Data Sheets (MSDS) are available at www.apple.com/environment/resources/msds.html.
•• alarming words I found are (some Power Mac G5 models), (unlikely event), (Avoid inhaling or direct contact with skin), (Dispose of all clean-up materials). . ahhhhh, why liquid cooled?

Processor removal help: G5 liquid cooled

I am looking for some help on removing the heat sync/ processor on a dual 2.5 with the liquid cooled unit.
The 8 CPU Heatsink Allen screws 2.5 mm. that sit in the "Lagshields" are loosened, but the CPU unit still is being held down by more fasteners?
Which other fasteners ( the torx screws?) need loosening to be able to lift the CPU unit free of the board ?
Has anybody done this that can remember the procedure.
Any help is appreciated !! -john

Thanks to all who provided help on this. I did in the end get a copy of the Service Source for the model I was working on (a late 2004 2.5 dual LCS Heat Sink model) which made all the difference. This document is essential. Thanks to a discussion user who had a copy! In my case I needed to replace a blown PSU (not an overly difficult task for anyone who is proficient in removing and replacing components)
While I understand the logic for Apple to not make this document too readily available I disagree with this strategy. There is nothing overly technical in this document and in the end people will be lead down the wrong pathe (and do more damage) if they cannot get good info. In my case I found all kinds of miss-leading info about how to pull the processor unit for my machine. Some said remove all the screws, others said just 4 screws (in fact there are 8) Some said don't do it it is complicated, others said it is no more difficult than an air cooled unit. Oddly Apple's site only showed the Service Source document for the earlier air cooled models, which is only helpful to a certain degree.
My point is that too keep things a mystery by not allowing good info to be had causes more harm. Maybe that's the intention ? Anyway I am big fan of Open Source, collaborative sharing of ideas etc. So forums like this are a big help.
Thanks again to all !!

G5 2.5 to 2.0 conversion to remove liquid cooling system

I've had a g5 2.5 with liquid cooling working well for a while now, but now doesn't boot into OSX. So I found the problem being a blockage in the LCS. While taking a part the death cooling unit I accidentally broke one of the cooling blocks and I've already tried everything from high end epoxy to jb weld to fix it with no luck. Looked into replacing it with another comp or parts and it just seems to expensive to replace just for one cooling block. So hear is my question, is it possible to replace the 2.5 g5 with a 2.0? I have the dual 2.5 from 2004 and wondered if the logic board is able to work with the 2.0 from 2004? I like the 2.0 g5 because it has no LCS, just heatsinks or could I use the heatsinks from the 2.0 on a 2.5? I really love my g5 and don't want to scrap it just yet.

Hello,
Sorry to hear this, but did you try Amazon or eBay yet? You should look into it. You might be able to find someone with a busted leaking cooling system, but the block is still good. =) Wish you luck.
Regards.

Portege R600 - Difference between cooling options

I have a Portege R600 with Windows 7 installed, but I guess my query is generic to all Porteges regardless of the version of Windows.
Could someone please explain to me what the different "cooling options" in the power settings actually mean? I couldn't find details anywhere.
Does battery optimized mean that the cpu fan gets activated only beyond a certain temperature? And what's the difference between cooling and maximum performance?
Is there any other way to set the cpu fan speed directly?
This is a very important point to me, because the fan of the Portege is terrible, too noisy, to the extent that I am considering return the laptop unless I find a solution. Sometimes it sounds like a Ferrari engine at a billion rpms!
Thanks!

This points to:
[http://aps2.toshiba-tro.de/kb0/HTD84026Q0000R01.htm]
which mentions that:
"If the sound of the CPU fan seems too loud, a setting that optimizes battery life will also cause the CPU fan to turn on less frequently."
However, my problem was quite the opposite: optimizing battery life causes the fan to stay off most of the times but to make the noise of a Ferrari engine at max speed when it activates. Optimizing performance, instead, means the fan is almost always on but barely noticeable, and never makes the disturbing Ferrari-like noise.
Maybe it's just me, but that kind of noise prevents me from using the laptop and would have cause me to return it had I not found a solution. I simply think that it's such a big potential problem that a clear solution should have been explained in huge letters, all the more so because the solution is very banal. It might be just my opinion, but judging by reviews and comments on forums, I'd say it isn't.

MSI Dragon Liquid Cooler

Hi all,
would like to ask if you have any info on what the hell is the MSI Dragon Liquid Cooler? Seen it on scan.co.uk for 40 quid (Pounds) but why does it come as an OEM and why MSI doesn't have any info about it on their website? Seen some reviews on it but they were just comments under product. Wanted to watch video-review, or comparison of it and e.g. Corsair h100i but no go..
Does any of you got it maybe?
Thanks

it looks like a standard re-branded Asetek made unit and is identical to a Antec KÜHLER H2O 620 closed loop cooler so i would hazard a guess its just the same within 1-2C as they both seem to have the same pump, Radiator, tubing and fans so it will be near identical unless there are changes to the CPU contact plate interior!

Check your computer if you have a liquid cooled G5

Hello
Please excuse this thread as not possibly being in the right category
I am trying to reach as much of the Mac community and alerting them to a defect in the liquid cooled G5. Below is my communication sent to Apple?
Check this site out: http://www.xlr8yourmac.com/systems/G5coolantleaks.html
My Post to Apple:
Apple should have notified me of the leaking cooling system problem. I could have taken it to them for a check before the Apple care expired.
Checking the sites I have found that this has been a reoccurring problem with the G5 liquid cooled system.
I have bought the Apple care on both my g5 ppc and my G5 imac. My imac warranty is still in effect.
I was told by the store that there is and has been no recall on the liquid cooling system and they can’t give any credit on the repair unless Apple care authorizes the credit.
With all the problems regarding the liquid cooled system, Apple should accept some of or all the responsibility of the this defect.
I have recently purchased leopard and installed leopard along with the purchase of iLife and iWork. I have spent considerable amount of money with the purchase of this machine. 2 23” cinema displays, airport, Ram pci cards and software Cs CS2 and plug-ins for Photoshop.
This computer has less than two years of operating time as it’s in my home in Arizona. I am only in this house during the winters.
Bottom line apple should have notified me of this defect so I could have had it checked at the store before the warranty expired. Apple should accept this defect as there responsibility and correct with no charge
Thank you for any considerations
My post on the apple discussion board:
Just took my g5 liquid cooled computer into apple because it is leaking and dripped onto my power supply. I am looking at a little under a thousand dollars for repair. This was my first Mac that I bought in November of 2004. Its out of warranty but has only been used 6 months out a year as it is located in my home in AZ which I am only there for the winters. (Less than 2 years of actual use) They told me at the apple store there is no recall and I would have to call the apple care people to try and get some help on the cost.
I am upset with this problem and had read that after about three years they start to leak. I thought I was in good shape until this morning.
They told me that the power supply could be bad also. They will order the parts and call me when it’s done.
I do feel apple should have some responsibility with this leaking and I will try to talk to them on Monday.
I should have taken the computer in just before the warranty was up had it checked.
I will post back when I have some answers
Dick

I just talked to applecare today and they are replacing my g5 with a Mac pro 2.8. They are matching all my upgrades that I had on my g5 that I bought from them. I can't commend them enough, what a great company to deal with. They recognize they had a problem and doing their customers right.

Welcome to the forum.
One of the issues with Widescreen material is that most 16:9 TV's, and even some DVD/BD players, have settings on how 16:9 material will be displayed.
As a test, choose Burn to Folder (on your computer), which will result in a VIDEO_TS folder with the IFO, BUP and VOB files inside (plus an OpenDVD folder). Use a DVD software player, such as CyberLink's PowerDVD, or the free MediaPlayer Classic HC, to play that VIDEO_TS folder. Does that software player display the material as 16:9, or as 4:3?
That should tell us if there is an issue with the VIDEO_TS folder's files and the PAR flag, or if the issue might be elsewhere.
Good luck,
