i7 720 processor
-
Hello friends,
I have a Dell Studio 1557 laptop, which is a laptop that has poor cooling and gets very hot. It has an i7 processor model 720 with 4 gb of ram. The issue is that I changed the thermal paste and put on some artic silver 5 that I had used about 4 months ago but it was covered with a cap, perhaps that's where the problem comes from. The first method I used was to first remove the thermal paste with alcohol and cotton and then I waited and put a drop in the center and then putting the heatsink I put it back together and the computer got hot. The second method was to disassemble the laptop again and what I did was put a little thermal paste and spread it with my hand with a plastic bag but it still gets very hot.I still don't understand why it cools poorly, I don't know if it was because that thermal paste was already used before, which I doubt is the reason. I hope for some suggestions.
Thank you very much

There are laptops that are hot by nature, thermal paste doesn't work miracles and if the radiator is too small, as often happens, the laptop will heat up and in principle nothing happens, although it is true that over the years they usually suffer less the cooler they are. There is little you can do, buy a base with ventilation and not much else.

Hello the problem is that since the thermal paste was changed it turns off at 2 mi. If a thermal paste is opened and then closed it doesn't lose its properties, right?
Thanks

It doesn't have to if it's not dry. Are you sure you've put the heatsink back correctly? It's possible that it's not making good contact. Apart from putting paste on the CPU, the heatsink usually also connects the chipset and other components. You have to check that everything is making good contact, that the paste is properly applied to all components, that it's exactly as it was, and also that the fan is working properly. You can check it by turning it on while it's open, so you can see that the fan is moving properly and that the heatsink is heating up. -
If I think that everything is perfect when I plug in the computer, the fan goes to many rpm, which did not happen before, it made me think that maybe it was the paste or the method I used.
Thanks

The fan is regulated according to the temperature, it is possible that if it is not working properly it will heat up and that is why it goes so fast because it cannot cool it down. Does it go full speed from the moment you start it up or is it a little later? What temperatures does the BIOS give at startup?
-
It goes full blast when you turn on the laptop, I told you before that the PC got hot, but now it gets too hot too fast, to the point that it turns off after a short time -
That sounds like poor contact to me. There are heatsinks that come with a thermal sponge that is used to make very good contact with the processor - chipset and so on, because they are at a different level and so they equalize. Maybe it's a problem with the chipset and not the micro. I've seen people who, with great enthusiasm, remove them without noticing that difference in height and the silicone, if it's not in a very thin layer, is useless. -

Don't think it's bad contact, that one is similar to an i7 920 with less frequency and some get pretty hot, especially the C1s, I have one with a Noctua with two fans in a case that can be considered well ventilated and it's at 55º without doing anything, even now with the heat it's higher.
I doubt a laptop heatsink would keep that CPU cool, what it could do if the bios allows it and it's not going to do important work is disable HT, because in a laptop it won't be able to lower voltages, it will surely lower the temperature by a few degrees.
Mine is years old and never shuts down even though you could fry eggs, so it could be a contact problem, but I should try disabling HT, which makes those CPUs get hotter.
You should also check that the heatsink doesn't have dust and doesn't allow it to dissipate better, because dust accumulates in the places where it takes air from outside and loses a lot of efficiency.

The problem is that before it would heat up and then rato.se would turn off, but now when I put on the artic silver it heats up so much that it can turn off within a minute and the fan is clean. I cleaned the thermal paste with alcohol, maybe it wasn't cleaned properly, the remains... I don't know, it's a mess. Thanks for your responses, maybe you can help me. -

Thermal paste is put in very little quantity, a layer like a cigarette paper, because if you put a blob it can be worse, put very little and spread it well, with a latex glove or a bag on a finger, only cover the DIE part, also maybe if you put too much it can short circuit, I don't know how that CPU is if it has or not IHS, the best thing is to put very little and tighten the screws in a cross shape little by little so that the heatsink settles evenly, I would also put non-conductive paste, even if it's more difficult to spread.

It's q I did it like this in small quantity like a video that was applied to a MacBook pro i7 but it turns off maybe it's x the remains of the previous paste I saw that there are some products called artic clean maybe that's why it's driving me crazy If you want I'll take a picture putting the paste and then we'll see the error -

hello. in all the computers I've had and I've changed the thermal paste on all of them, I've never used any "cleaner" I've always used paper towels and alcohol, first just paper (to remove the thickest) and then paper soaked in alcohol until the HIS is clean
on the left a 9950 half clean on the right a 965 new from the box
regards
P.D if it's dirtier than the 9950 then you haven't cleaned the HIS properly -
Look I think the problem is with the graphics card, I also changed the thermal paste on it. How do you apply it? I took a screenshot of Everest and this is the result. I also applied thermal paste to the CPU and the graphics card. I look forward to your responses, thank you very much.

hello, with this I'm sure I won't damage my eyes (on the lady on the right, if you click on the image)

At first glance, it doesn't seem to me that it's excessively hot either, at least not so much as to shut down... The GPU at over 100º is suspicious, but I wouldn't rule out the physical failure of a component, or even the temperature sensor being broken, which wouldn't be the first time it happens... Best regards -
The gpu according to the sensor reaches more than 100, the cpus are perfect in temperature but no matter how much thermal paste I put on the GPU it continues to heat up a lot, the pc doesn't know how to fix it for real. The problem is clear that it is of the cpu I need help. Thanks

Look, regulate the fan with EVGA precision or MSI afterburner, if the graphics card is NVIDIA, either one works, if it's AMD, afterburner works. You can make a better fan profile, but it's not recommended to put artic silver on a graphics card, it's better to use non-conductive paste, although I have put it on more than one, but they were desktop graphics cards and the GPU had an IHS, but it's usually better to use non-conductive pastes like Noctua or MX 2 or 3.
