Ran it from cold, I hear the fan going on/off but it just isn't very loud. Think your fans must be bust.
When I turn the laptop on, the fan blows like a hairdryer on full power, for about a second. I think this is part of the power on test. Anyway, it goes off while the laptop boots.
Is that loudness the level that you hear when it's cycling on/off?

That's normal: As long as the fan control is not fully initialized, the fan must run at full speed in case the components should be/get hot.

No. It seems to be a bit louder as when the fan is continuously running on low power (almost idle system). But this On/Off brings the sound of the fan more to the attention then a constant noise of the same loudness. And: It is not necessary, the temperatures are low enough that the fan could even be silent.

Wowsers!!! my cycling sound is quieter than the boot up burst. If yours in louder than that??!! no way are we talking about the same volume levels. It's a hard thing to quantify, but I hope this helps.
If it's loud enough to be heard over a phone line, which mine is not, then you can easily let a tech listen to it. Thats gotta be a knackered fan.

I think you misunderstood something.
Boot-up: Fan at full power, full noise (lets say: Noise level 10)
Fan running but at (almost) lowest level (eg. when system idle and fan not switching between on/off in short intervals): Noise level 1
Fan switching between on/off in short intervals (50/20 seconds or something llike this): When fan is on than noise level 2 but it is disturbing as if it would be noise level 4 continuously. (When fan is off, than noise level 0.)
By the way, with my previous notebook, a dual core introduced about 3.5 years ago, the fan was off when the system was idle. The general noise level of the Studio 1747 is higher than the noise level of that dual core notebook. However, the noise level of the ST 1747 is still well below the expectations (the fears) I had, when ordering a notebook with a 45 W TDP (thermal design power) processor.
Dell should be able (and aim to) resolve the on/off cycling of the fan. I believe, the fan could well be switched off, when the system is (almost) idle. If not, just let the fan run at lowest speed (the noise level then will be low enough that the fan can be overheard after some while).
I cancelled my order today after reading about all the issues.
Really dissapointed but glad I read about this before I received it.
Shame. Looks like some resolution is about to come to light with some of the issues plaguing ST1747 users. http://forum.notebookreview.com/showthread.php?t=446193&page=174
Got mine yesterday - decided to test it, and if... send it back! In DK we have 2 weeks to return..
Until now its ok! Only thing is that my TC Konnekt 48 firewire Audio inteface won´t work with this laptop, even with the newest win 7 64bit driver...??? Don´t now if this is at firewire/Dell problem or a TC electronics driver problem - I´m still working on it!
When running Audio sequencer software - the cpu works fast and smooth, stady 2,66 ghz for several hours... I know that the liste speed id 2,88 ghz, but until now its ok with me - the laptop isn´t getting warm...and the power supply is even colder than the previous ones from my HP DV9004eu. Later on I will messure some temps..
If any one experienced firewire connection problems - pls reply!

So would this mean that dell now agrees that the 90w adapter is insufficient and will replace them with 130w adapters?
I have now recieved my 1747 and even with the problems im quite happy with it, ive not stress tested yet but last night i did run gta4 on it with maxxed settings whilst copying 100gb of data to the laptop from a usb powered hard drive and it didnt seem to be bothered, certainly wipes the floor with my previous acer 6920G.
Also i did notice that in the bios (shipped with A05) that it recognises what power adapter you are using so in my case its the 90w, does anyone using the 130w adapter see any change in its status and does it mean anything at all?
The bios can recognize a 130 watt adapter but it can't yet use the extra power. You will still be limited to a maximum of 90 watts. It looks like Dell is ready to start taking this issue seriously and will update the bios so you can take full advantage of your computer when using a 130 watt adapter.
If you still have your Acer 6920G then give ThrottleStop a try. We recently discovered that Acer has been using Chipset Clock Modulation on their laptops but ThrottleStop can be used to reverse that. Finally users are able to use their Acer laptops at very close to their full rated speed without any throttling.
:emotion-1:This is the text of "Dell Bill_B" 's post in the 1645 forum after his conference call with Dell engineers::emotion-1:
Re: S-XPS 1645 Throttling Info. and Updates
Now for my promised update and answers to the questions I had gathered before the call. Studio 1747 owners, we talked about your throttling issues as well and will share details on your threads. We expect to see the final fix for you sooner than the 1645/1647 owners.
Firstly, let me talk about what I am not prepared or will not talk about first.
Killawatt findings- We use different tools and methods to measure total power draw the system takes from the AC adapter, so I will not be addressing any questions or counterpoints based on findings derived from Killawatt meters.
Japanese replacement AC adapters- there are some factors involving 3-prong to 2-prong adapters that we currently do not stock, so you folks may be waiting for the additional time it takes to design and get line of sight to parts supply. Sorry about that.
Now for what I can talk about.
We will get into our benchmark findings in a little more detail on Direct2Dell at a later date. We plan to pull some specific posts from this thread and address them there in detail.
The A-rev of BIOS A07 went to test today. Once it passes testing, we will web post it. We will begin the process of sending out 130W adapters at that time. We will take NBR and DCF members to PM and get yours to you, so you do not need to call in. We will let other users know when the Direct2Dell post goes live how we will be getting them their adapters. It may or may not be a proactive replacement. The adapters will be the slim models and not the bricks. General sentiment is it should be proactive, if at all logistically possible. We do not have an ETA for factory cut in for A07 and the new adapter (in other words, for the orders that have not shipped yet). We will post details on the ETA for factory cut in when we get them.
The questions I had from the NBR community that I was able to get answers to:
1. Is this for all regions? yes. Depending on regulatory requirements per country, the timelines may vary.
2. What about 1647? We will need time to look at closer. Component and chipset factors are different and need a seperate investigation. I am sure the timeline will be a little quicker than it was for 1645.
3. What about customers who bought their own adapters? This really was not a question for the engineers to answer. Among the non-engineers, there were 2 different opinions. We will discuss the question tomorrow and get back to you on this one.
4. Will the bios officially allow the use of 150W adapters too, since laptops with RGBLED and i7-820 (like mine) are more power demanding of a WLED+i7-720? Or 130W will be the only choice? 130W is the only adapter needed. You can use a 150W if you like, but it should make no difference.
5. Can the customers have better release notes on bios and driver updates? The engineer could only answer for this platform, but he assured us he will take this question to the team and do his best to make sure the notes are more informative for the next BIOS release.
One more thing: I brought up the exhaust vent question. This will have to be opened as a seperate service request. I will get that in the works. We had the same problem with Studio XPS 1340. We wound up designing a new exhaust vent cover that fixed the problem by pointing the exhaust down. On my test 1340, I just popped the cover off and ran around with a gaping hole there until I got the new cover. It worked as a temporary workaround, but it was a little goofy looking.
Last edited by Dell-Bill_B : Today at 06:12 AM. Reason: one more thing
Notebook params: FULL HD screen, two 320 GB (7200 rpm) hard disks, core i7 720QM and a 90W poer supply and a couble of USB devices on power port...
A have already done the A05 BIOS update, too. I have a Windows 7 64 bit installed. I have used the following SWs for testing:
- ATI Tool (scan for artifacts)
- Intel Burn Test with 8 threads
- CPU-Z for monitoring CPU speed
So, full stress (100% processor, and video load), background light at full brightness..., throttling downto ~1400 Mhz, i think its ok with this BIOS.
I disconnect my 90W power supply -> processor speed goes up to 1600 MHz, seems stable.
Now, i connect the power supply again. Guess what happened?!... suddenly turned off! Okey, i whispered a little pray before i turned on my notebook again. Huh.. Windows is booting up, my desktop appears... but, accu failure, Windows was saying about HW failure, and i need to buy a new one or something like that... link to dell shop... great!
Shutdown, unplug PS, connect again, start, same failure in Windows.
Turn off. Remove battery. The little LEDs are saying, fully loaded. Accu back, turn on, and.... everything works fine, accu 95 percent loaded ( i think 5 procent was the hungry of the full load).
I wish i had a clue how much power swallowed from accu at full load, i suppose it was more than 90W...
So, is it normal? The BIOS does realy protect the accu? Was it a single occurence? Dont know, i did not want to try it again....

So the 1647 will get a new 130 watt adapter while the 1747 will not and will only get an BIOS update to take care of the throttling.

Hello there,
i have got a strange issue.
Notebook params: FULL HD screen, two 320 GB (7200 rpm) hard disks, core i7 720QM and a 90W poer supply and a couble of USB devices on power port...
A have already done the A05 BIOS update, too. I have a Windows 7 64 bit installed. I have used the following SWs for testing:

I disconnect my 90W power supply -> processor speed goes up to 1600 MHz, seems stable.
Now, i connect the power supply again. Guess what happened?!... suddenly turned off! Okey, i whispered a little pray before i turned on my notebook again. Huh.. Windows is booting up, my desktop appears... but, accu failure, Windows was saying about HW failure, and i need to buy a new one or something like that... link to dell shop... great!
Shutdown, unplug PS, connect again, start, same failure in Windows.
Turn off. Remove battery. The little LEDs are saying, fully loaded. Accu back, turn on, and.... everything works fine, accu 95 percent loaded ( i think 5 procent was the hungry of the full load).
