JHL90 Temp Issue

I own a Compal JHL90. I got in it a P8400 and it has a 9600M GT GPU. The GPU seems to idle at about 60°C and can go up to 90°C or more when running graphically intense programs.

I have read another article on this, and apparently it seems normal. The only reason I am concerned is that I believe it to be the thermal paste. The GPU seems to raise in temperature fairly quickly and can drop 15-20°C in about 30-50 seconds. So what do you guys think??

Thanks.

 

Thats not totally normal. Its in the safe area, but barely.

60C is a little warm for idling, and you dont want your GPu any more than 90C at max. So, its a little warmer than it should be.

Re-applying Thermal Paste could help a little.

You may want to look into a Notebook Cooler. See my Aeolus Review in Sig.

 

Nice review thanks. Ill look into a cooler.

The only reason I haven't replace the thermal paste thus forth is because it seems that I'd have to take off the entire bottom of the case to gain access to the GPU. I only have access to part of the GPU the rest is hidden under case

 

Yeah, its not the easiest task to redo thermal paste.

Your Welcome, and thanks.

 

Has anyone here that owns a JHL90 redone the thermal paste on the GPU???

If you have I would love some pointers. Thanks.

 

Ahl395, do you own a JHL90 to give such certain advices? I would agree on the cooler part, but just to let you know, these temps seem to be NORMAL for JHL90. Mine is quite new, and I never seen the GPU going below 56 idle, and i've seen it hittin 94 as well.

I was thinking about reapplying the paste, but usually I wait for at least 5-6 months before taking my new laptops completely apart. With JHL90 thats exactly what u need to do, you can't just take one cover off and get access to all the guts

 

No, I dont. But its a common known thing that its not the easiest thing to do, to redo thermal paste on a laptop. Mainly because its complex to get to such components.
As you pretty much supported:

They could be normal for a JHL90, but over 90C is not normal for a Graphics Card.

 

@NJoy - have you redone the thermal paste yet?? I could really use some pointers if you have. Anything you have done to lower temps?? I may invest in a cooling pad but would like advice from an HL90 owner first hand.

Thanks again for your help guys!

 

Investing in a cooling pad might be a good idea in the long run. The problem with JHL90 is that the GF9600 has a bit of room between itself and the bottom cover, also, there aren't many ventilation holes that would deliver the air to it. Vents for RAM and HDD don't count. Still, trying a cheap cooler i saw about 5C drop in temps.
About AS5. AFAIK PCSpecialist do use AS5 for the cpu, but i'm not sure whether they do the same for the graphics card since they get their barebones prebuilt, i guess. I'm a bit hesitant to do it right now, the laptop is only a month old and the only paste i have on hand is Akasa 450, which is crap compared to Arctic Silver. I might do it in a couple of weeks, when i get a bit of spare time. If I do, i'll also make a dismantle guide for others.
At the moment i just raise the back of the laptop by puting a pack of cigarettes under the battery when gaming, it helps (87 max so far). BTW, 94 I hit at 640/519, just on the edge of stable clocks in my case.

I will also check the temps of my friend, who's got exactly the same machine but running XP on it. Will post 'em later the week

 

I have an JHL90 myself. Idling temps for the GPU are between 57 and 62 degrees, onder full load for about 2 hours it reaches a maximum of 94 degrees. There is almost nothing to do about it...

 

has anyone on here that owns a JHL90 re-applied the thermal paste on the CPU??

And I also have a question about the fan speed. First off is there a way to control it??? And it seems the fan speed is based mainly upon CPU temperature, can anyone confirm this?

 

No you cannot control the fan speed and yes, you said well, it based mainly on CPU temp. but also on GPU as well. For example my fan kicks in the highest speed when GPU is on 90C. Other steps are based on CPU. Step 0(off) is on 49C, Step 1 is 55C, and step 2 is on 60C. I'm can't say if there is a step 3, I didn't pay attention.

 

splashpants
It's based only on CU temperature, you can burn your VGA and BIOS won't even care.
The only way to make fan spin slower on load is to loware voltages with RMClock. Ussualy you can get - 8-10 degrees by doing so, but VGA will only suffer more then.
Well, it's what happens on xFLxx based rigs.

 

Why does my fan kicks in the highest speed when the GPU is 90C and CPU is like 56C(not for the highest speed)? I've been testing this with ATITool.

 

ATITool? I thought this was all intel/nvidia??

 

No it's not, try it. At first it was I think, but later they made it to support nvidia as well. Great tool for overclocking. Can find your max core/mem clocks, even though I do it myself.

 

WOW! I did check it out and its a pretty awesome tool! Kinda decieving though, using ATITool on an Nvidia GPU.

Thanks!

 

heh, my friend's JHL90 with XP is having idle temps of like 73-75C, but it doesn't reach 90 when gaming, weird))

 

idle temps of 73-75 :O

Ya mine sits at about 60 and can get up to 92 when gaming for over an hour.

 

I have JHL90 too, I was playing and it went to 105 :O, then I took it where i bought, they changed the heatsinks and paste. It 's now max 96 when gaming. Idle 60-65. On table i took off the cpu cover that it could take more air, it helped a bit. But the problem is still bad, over 90 is too much i think.

 

lol I agree. I am thinking about ripping the bottom of it and removing all the heatsinks and trying some arctic silver... only problem is I don't want to take the bottom off because it looks like quite a bit of work.

 

What do you use for temps monitoring? And whats the ambient/room temp?

 

i've used speedfan... even though I don't have access to fan controllers

Under linux there a bunch of cool utilites for monitoring GPU... though the best is built right into the driver! The ambient room temp is probably about 68-72 farenheit.

 

I used everest for temperature logging. Room temp was 18-23 C i think.

 

Well seems like the temps are lowered nowafter you changed the paste and the heatsink and in normal range as what other users say. So I don't think you should worry.
You can try with various drivers or for probably best results use nvidias newest drivers for notebook as desktop drivers tend work with higher temps.

One more thing, did you overclock your card?

 

no overclock, didn't want to try it with those temps.

 

lol don't blame you. Perhaps you should look into a cooling pad.

What do you guys think would be an adequate cooling pad for the JHL90??

 

after installing W7 x64 bit my GPU idle temp. raised to 60 C even without driver!!!! am not gaming ........

can you please post your gpu temp.

 

~65 C is the normal idle temp for me. The fans don't even start until well past 70 C.

 

when i purchased i 7 months ago the idle gpu temp. was 55-57C

then how much it will reach if you play crysis or intensive games???

 

Has anyone changed the thermal paste of the gpu?

In manual it seems pretty hard. :/

 

applying thermal compound is pretty easy... just need a small amount (dont use too much or it wont improve anything)

the Cooling Guide has a simple outlook on this.

 

its not the thermal paste thats a pain in the you-know-what... you have to take the ENTIRE laptop apart to get at it. i was reading the disassembly guide and it is quite a bit of work just to get the vga card out :S

 

its maybe difficult but the pain of the process is well worth the effort in the long run....u rather spent an 1:30mins opening and reapplying thermal paste or let it overheat and have hardware issues later in time which will be more difficult to fix due to the whole process of it being maybe still under warranty that u have to mail it to them that 4 days .......to get their then the diagnosis 5...... more days then 2 days......... to get back to u about the problems..... then 1 week so they can send it back to u...... and knowing they didnt do squat................ IMO

 

LOL... i am assuming everyone here recommends arctic silver?

 

I don't think that thermal paste will make any improvement.
I ve a cheap cooler pad.. its too cheap so it barely makes a difference.

But with an hp I have I used an improvised cooling method:
I located a heating fan(the ones to warm your room) on the back of the laptop and turned it on just on fan. An inclined the screen so wind would flow down to the base of the computer. Incredibly i was able to lower 40C!! Well... my drive overheats a LOT.. like 75C (preety critical for a hd) and i got it to 35C.
When i get to home i will upload some photos and screens of temp monitoring. Oh... and also try it with my JHL90!!

I got up to 96C from the VGA.

Bye!
Be cool

 

wow really?? Thats pretty intense difference. post those pictures if you get a chance... that would great!!

 

what temp monitor could i use that makes a graph temp-time?

 

@neTed - You can use Rivatuner.

 

or speedfan

 

These temps seem insanely high. The only dedicated gaming laptop that I've owned was the Asus G1S, and even it wasn't as hot as the reports here.

The other Montevina laptop that I had was a Sony FW that idled at 35C! Nice!

 

when the jhl90 was built I don't think they really took cooling into consideration... because there isn't really a huge design difference between their integrated graphics cooling and the dedicated graphics cooling. The cooling is quite pitiful, however I think that it could be improved greatly if the fan speeds were setup better!

 

anyone tried undervolting their jhl90?? success? also what laptop2go video drivers do you guys use with your comp to reduce GPUheat?

 

Its not undervolting the CPU that will make any difference. I am not even sure if you can undervolt the GPU.... and as for laptop drivers I just download them straight from nvidia's driver download page.

 

my left hand gets hot after 1 hour of gaming ... =[

 

lol ya you gotta be careful were you rest your hand. Try seeing if you can stick the corner of a mousepad on it or something. And take out the express card filler so some air can get in there... and if you have a fan you can definitely blow some air in there. LOL

 

hehe how do you take out that express card filler?? its so jammed in there..

 

Press it in a little bit, than you can take it out. It works on my FL90 which should be pretty identical in construction. However, I don't think it will make a big difference ;-)

 

How warm is the laptop to the touch, unbearable or not noticeable?

Also, how is the battery life of this laptop, can it achieve 4 hours of normal surfing and word processing?

 

My JFL92 now in summer months has HDD temp at 50C just by surfing. I guess that if I play games it would get even higher. Check your temps with Everest.
