dell inspiron 1520 heat?

hi, I just got my 1520 and tried to play world of warcraft and the heat of the CPU went up to 70C.., Do laptops normally get this hot? I want to play CoD 4 and Crysis but i'm worried the laptop will get too hot, anyone know if it will? Should I get a laptop cooler?

My specs are:
2.2 ghz
2gb ram
8600gt

From all the reviews i've read, they all said dell never really got hot so is something wrong with my computer?

Thanks, any opinions and advice would be appreciated.

 

i think should be alright. my T7500 2.2GHz at peak (stressed) is around 70+-1C too. GPU at peak 68C. any others with better result?

 

Darn... I just sent my HP back, (see sig) for a new motherboard/cpu as it quit due to high heat, 50-60C range. I was planning to sell the HP as soon as I got it back and get a 1500 series notebook. Now I'm not so sure...

 

yea, i returned my hp well because dell had a better deal and i heard hp had heat problems and dell not so much so dunno now

but hey alexnvidia, how long have you had your laptop? have you played any new games and has the laptop like crashed or locked up or anything?

 

I've been having heat issues with my laptop as well (1520). I'm starting to think the model number is a goal for the processor heat-wise.

( http://forum.notebookreview.com/showthread.php?t=206019 is my whine thread about the issue.)

I've got a replacement fan on order from Dell, it was supposed to be here today but my area's DHL service is terrible.

Keep it on a cooling pad, and run 18kfangui. If you can handle the perf hit try running it in power saver. I've taken to running the laptop without a battery in it, just off the AC adapter (mine stays on a desk most of the time).

But really watch it, mine has gotten so hot it warped the first keyboard. :/

 

well I read in a thread below 85C is okay so i feel better but was yours past 85C when you first got it? or did it take some time of usage before reaching your 95C in your thread?

 

85C is NOT okay. That is way too hot and over time it will damage parts like your motherboard, cpu etc. Heat is the biggest wear and tear on any moving parts. 85C is way too hot. I definitely don't want a 1520 now.

My notebook was averaging 55-60C for months and why my motherboard/cpu/wireless needs replacing now...

Anybody knows what the average temps for the Dell 1525 is?

 

got a vostro 1500 here (identical to the 1520) and i'm getting around 49C when idling for a few hours, fan turns on with low rpm at about 51C. After playing HL2 EP2 for 2 hours i was at 60C, but i use RMClock to run my T7500 with only 1,1V VCore at 11x multiplier, so it doesn't get as hot as it would normally.

@jack53: the Core 2 Duos are specified up to 100C, so why do you think 50-60C is high? it always depends on what the components are specified to... if the CPU was specified to run only up to 70C, then 50-60C would certainly be bad

Yes, maybe some cpu's can handle that heat, but motherboards and componets can't handle that kind of heat over time .

Heat wears and/or destroys anything over time!

 

wtf your vostro was only 60c with HALF LIFE 2??? it's got core 2 duo too doesn't it?? why is mine so hot

 

you forget, that these temperatures occur in the cores of the CPU / GPU only, the system itself doesn't heat up more than about 40-45C at hotspots. Look at this thermal measuring of the system under load: http://www.notebookjournal.de/storage/show/image/image46b9f6a119bd4

Even though you're right that heat wears out stuff over time, i never heard of a laptop that was "worn out" because of that, have you? The only thing that could happen over time is that the air flow could get restricted due to dust etc. so that the laptop would overheat.

 

as i wrote, i undervolted my Core 2 Duo T7500. normally it runs with 1,25V at the 11x multiplier (2,2 GHz) but mine is restricted to 1,1V so the CPU doesnt produce as much heat as it would normally. I wonder how warm the thing will get in summer, when the ambient temperature reaches about 30C... THEN heat will be more of an issue

 

had my laptop for 3 months now. OC the graphics to 650/500. has been smooth sailing all the way with any kind of hardcore games out there like crysis, call of duty 4, bioshock, etc..

so i guess that is the safe operating temperature.

 

he undervolt his cpu. your 85C is arguably a little too high. you might wanna do something about it. what's your ambient temperature?

 

I'm assuming your comments were aimed in my general direction.

My 1520 started off in July just fine, idling in 35-40c depending on ambient room temp, no big deal.

In November it started idling at 60c+ 90% of the time, so I cleaned it out thoroughly, with no effect. I built my first cooling pad, it worked ok for a while at bringing temps down. Contacted dell, they sent me a fan overnight (to this day DHL has still not delivered it).

In December I got my first pink screen after system got hot enough to warp the metal backing of the keyboard tray. Pink/Purple screen is from a heat damaged video card is what I assumed. Contacted Dell. They send out a box for the laptop to ship into Depot for repairs - DHL delivers it to the wrong house, and leaves it on the sidewalk in a rainstorm, box is destroyed. Dell rep yells at DHL rep on phone while we party line (supposedly, it was probably his cousin or something) they ship another box overnight - DHL still hasn't gotten it here.

After 3 hours of being on the phone with Dell, on Monday they overnight a fan and a new video card. I am assured by DHL, Dell, God, and St. Christopher that the package will be here no later than 7 pm on Wednesday. Like a sucker I wait around all day for them to no avail.

I live just outside of Round Rock, TX (which is where Dell's HQ is) and I'm getting to the point where I'm debating turning the laptop on in their lobby and letting it burn them down (I kid, but still).

I used to be a Dell fanboy of sorts, but this has really turned me off to any of their products. Of course I say this knowing next month the Dell OMG3000x will come out and I'll be drooling once again.


***

I should add that my experiences are possibly wholly unique - even the other laptop purchased at that time doesn't have the same problem (I assume if it did I'd hear about it as I work for that laptop's owner).

Squeaky mouse gets the hammer and all that jazz.

 

You haven't been around notebooks much have you? I don't care what YOU say, but 70-90C is too HOT and will damage your components over time.

 

jack53, stop giving people bad advice, you're loosing credibility every time you post.

My 1520 temps:
CPU - No load: 32C - 57C
CPU - With Load: 60C - 71C
GPU - No Load: 32C - 47C
GPU - With Load: 50C - 60C

Those are very normal temperatures, regardless to what bone head here says. When I say, with load, I'm talking about running games, like COD4, UT3 etc.


The Core 2 Duo's processors have a threshold of 100C. When the processor gets that hot it's designed to down clock all on it's own. To lower is temperature. If it is unable to lower is temperature - THE COMPUTER WILL SHUT OFF. When it does, that, that is when you know it's getting too hot.

The NVIDIA 8 Series cards have a threshold from 110C up to 140C. Just like the CPU, when the video card gets too hot, it will dowclock to lower it's temperature. When that fails to lower the temperature, THE COMPUTER WILL SHUT OFF.

So unless you people suffer from computers shutting off, without warning then you don't have to worry about heat. Go on NewEgg, Tiger direct, look at cooling pads, and look at the comments people leave. You'll see many people with all types and brands of computers saying they would turn the machine on, and simply browse the internet, and the machine would shut off.

So that alone will prove to anyone doubting me and saying I'm lying about the computer shutting off when it gets too hot.

Anyways,

You're CPU shouldn't be really going over 77 degrees in the 1520 regardless. Because with and without a cooling pad, has my CPU EVER gone over 72 degrees. So you may want to get it looked at or clean it out or even invest into a cooling pad.

As for 'Safe' temperatures, as long as you're CPU stays below 75C-77C, and the GPU stays below 80C, you're fine.

It is true, the hotter you're machine is, the less time it will live. Heat destroys the components and kills the performance. But saying common temperatures are 'too hot' is just stupid. You gotta remember you got two processors in there, and a high end GPU.

And jack53, if that's so true, then why is my 3 year old Voodoo machine, still running perfectly normal when it's CPU is running at 85C and the GPU around 75C-95C degree temperatures? If those temperatures we're too hot regardless, then why is it still running like a champ - 3 years later?!

By the way, if it's the Compaq you're talking about that you had to get all these components replaced due to heat problems, you're wrong. It's not cuz of heat, it's because Compaq suck... And the fact computers can fail at any given time without warning. So stop spitting out you're crack pot theories because it could be one of the millions of factors why you're machine failed and suffered problems.

the 1520 does an amazing job throwing heat away, anyone that disagrees needs to get their reality into check. I can't wait to see how much people complain when their mobile 8800's reach 80C, And think the world is coming to an end... lol

If you want a cooling pad, look at the Zalam ZM-NC1000 - Best cooling pad ever. It blows cool air under the entire notebook base surface. Looks great too.

 

Stop being ridiculous. You can't just cover your ears against the facts and stick your head in the sand.

Listen to B2TheEYo, nvidia cards have a temperature threshold of over 110 degrees celcius.

I'd say that anything below 85 degrees celcius at maximum load is not a big problem. However, if you're reaching those temperatures, you should clean out your ventilation system.

My notebook never goes over 70 C (because of the excellent cooling system) but my previous notebook would commonly reach GPU core temperatures over 90 C and it still lived more than 3 years. True, it's very uncomfortable at such high temperatures, but the boiling point of water is not even close enough to kill metal.

The temperature reading is at the core of the video card. The rest of the system will never see such temperatures.

 

Well.. you guys with the heads in the sand will find out after a year or so when you have to send your notebooks in for repair when they quit working.

Running at 90C or so is too HOT! PERIOD!

 

Thank you Cthulhu

Yes, it can be uncomfortable and uneasy to see those numbers.

And yes it is within the core, I forgot to mention that. Heat rises, remember that, so the heat won't get the chance to go 'down' into the motherboard. It instantly runs up into the heat sink. Some of the heat is transfered to the mother board and such yes.

But if it was so much heat that it could cause damage, wouldn't the plastic socket the CPU is sitting in melt before the metal and PBC components do?

Exactly.. lol.

 

lol..

Read my post,

If you're below 80, you're not gonna hit 90 you dork. If anything I agreed 90 is a bit to hot. But even at 90 degrees, you're still within the threshold. A threshold, Intel implemented. And I think the people who designed, and created the chip would know what's best compared to a crazy consumer (you). LOL

 

cool that sounds nice and you even overclocked? what kind of settings do you have on call of duty 4 and crysis? well mine hasn't hit 85C yet, i just saw on a thread that because of the core 2 duo limit of 100c, below 85C is okay to have. What is ambient temperature and how do i check it?

 

My Vostro 1500's CPU, T5470, was also climbing upto ~75C when running Orthos. But I was able to reduce that temperature to ~63C by undervolting to 0.925v using RMClock. Of course, undervolting is just like overclocking, YMMV. But it is worth giving it a try, saved battery life is the additional benefit. Kill-a-watt tells me that Laptop is using 10% and 20% less power with RMClock when the CPU is idle and loaded respectively (no GPU use).

 

what actually is undervolting? is it hard to do or is it easy? sounds like you get a lot of benefits by doing it, are there any disadvantages to it? will it hurt my laptop? if not it sounds like something I would like to try
what does YMMV mean??

 

60c is fine. Capacitors go up to 120c. Many, many other laptops have their CPU's hitting 90c full load.

But for the dell specifically, you shouldn't be that high.

I hit 65c full load with Orthos. (thats with my 1.5GHz though)

 

Undervolting is supplying less voltage than normally specified to CPU. It is a little time consuming to find the optimal minimum voltage that the CPU is stable, otherwise the CPU, and laptop, can crash randomly. The benefits are, specific for my case, 10%-20% longer battery life, and 10-15C lower CPU temp. YMMV means your mileage may vary, this is because every processor is guaranteed to work at only specified voltages, each of them will have different lower voltage limit. There is no risk to damage the hardware by lowering the voltage but you might lose data or corrupt the harddisk while testing the low voltage limit. I have done this on two different laptops, on my Inspiron 500m since several years, and my Vostro 1500 recently, and did not corrupt the harddisk or lose data.

cool thanks, i might try that

 

I took a little time to read all of these posts about overheating CPU's because I have actually run into the same problem. 1520 processors have new bios as of febuary 2008 which (suposedly) fix some of the temperature controlls, and add support for newer processors etc. Today I was told by dell before going any further with the complaint on my heat issues to flash my bios and i'll get a call tomorrow to confirm if anything has actually changed. The only thing that i notice is that the fan kicks on mid speed at 50 instead of 60, and it goes to high around 72 instead of 80. Besides the fan kicking in at the different temperatures nothing has really changed except it takes all but 5 secconds longer to overheat.

My T7250 will jump up to 80 to 90 degrees durring a mathematica program in under 10 secconds, and in a C# program it will jump up to 80 to 90 degrees in just about the same time. My GPU and my memory temperatures don't fluxuate much at all +-3 degrees or so from idle to full load (Geeforce 128mb), but my CPU scares me. You say thats the temperature inside of the cpu itself? I think thats highly doubfull because when i pick my laptop up and stick my hand under it it literally burns my hand so I know its too hot for the motherboard. It literally feels like a singing iron on my flesh, and I am going to have the whole system replaced asap before my warranty expires. I noticed the heat issue ever since I got the laptop, but I never actually ran a temperature program that reads the internal sensors untill short ago when I had my laptop on my knees and it literally burned my kneecaps. I do not like how hot it gets at all, its like having an old desktop w/o a fan in it at all. My old desktop's hard drives used to get singing hot aswell and they didnt last very long at all.

The temperature just raises way too quickly, and the fan inside of it doesn't handle that temperature. I have tried those fans that go under the laptop that push more air through, but they are honestly as useless as the fan that is already in there. I am sure by the end of the year this laptop will be warped, or there will be a fire hazard or something... Which I wouldnt mind suing dell for but I surely don't want to have it go that far. I am sorry but it should not operate just under the temperature that water boils at...

 

When I upgraded to a 2.0 Core 2, I was hitting temps of 200F or slightly north of 90C. It kept going into thermal shutdown - but that was because of a hacked up heat sync.

You should get a good thermal compound for the CPU. I did and now during an instense 4 hour gaming session of Call of Duty 4, I won't go above 160F or 70C

 

I just did a quick test with Prime95 for maximum heat generation: I let my system run 10 minutes on full load on both cores, after i've been using it for 3 hours to warm it up.

After 5 minutes the temp reached 66° and stayed there at medium fan speed. At 10 minutes it was still swaying between 65-66° on medium fan speed.

I have Arctic Silver 5 on my CPU (applied when i did the headphones fix) and with RMClock my T7500 runs @ 2,2GHz (11x multiplier) with 1,1V instead of the stock 1,25V.

Something is definately wrong with your system, i would nag as long at dell until you're satisfied
As long as the Vostro 1500 stays on a desk, it's pretty cool and quiet. On the knees i can't bare it much, even with the undervolting, but that's due to the hot air getting out BELOW the laptop. I think letting the air exit out the back like with macbooks is a much better solution.


Hope dell can resolve your heater

 

I have a 1520, I'm getting 57 C at idle... I don't know whats the problem
