  1. it seems like you tried everything you could....100c is def the reason why the game lags its dropping down the clock to prevent damage...were the temps this high before you applied the thermal paste? maybe you put too much or not enough
  2. and my GPU fan 0 RMP does that means your gpu fan is not working
  3. ^^ thats a good could just mean that there is one system fan for both the cpu and gpu too
  4. Thanks for the reply and yes my fan is working i can feel the air cming out through the back of my laptop but speed fan shows 0 RMP and about thermal paste yes i applied enough as i was with some 1 who service laptops . i have 1 question though do speed fan show all the fans in my laptop coz it only show GPU fan and nothing more.
  5. if it is the only sensor the laptop have it will show the one he read try this maybe you will get some readinds if there is a sensor on the gpu fan
  6. if you know that the fan is working then why do you need speedfan to monitor the fan speed?

    I tried the software u told it showed my motherbord fans r working but in graphic card it dint mention any fan i copied and pasted the information it gave...
  8. yea its probably not going show a graphics card fan bc its a laptop so it probably only has one system fan
  9. so laptops dont have graphic card fans okay is there anyway i can stop the over heating??

    You need to clean the heatsink. Laptop heatsinks collect hair and dust like mad.

    Try to use a can of compressed gas(air duster) toe blast air into the vents to dislodge the dust/dirt. If you can actually see the fan on the bottom, see how dirty it looks.

    If it gets too bad, sometimes you have to take it apart(or get someone else to) to clean it better.

    If it gets too bad, it start to look like this.

    Laptop video cards do have a fan, sometimes its own, other files shared with the cpu.


    Somehow i missed that you DID clean fans, did you check that side of the heatsink? it builds up like a fabric
  11. as nukemaster said you should def take it apart to clean it...I know you said you cleaned out the fan...did you get in there good? I will guess that you took it apart bc you said you re did the thermal paste so you might have taken the fan assembly apart
  12. yes i took them apart and cleaned them , there were some dust but i cleared them , i can even feel the heat cming from below into my keypads and left top aswell my laptop is dell studio 1558 . i have no idea y its over heat like this ><
  13. Best answer
    did this recently start happening or did it always do this and you just didnt notice it? its possible that its a bad design by seems like you ruled everything else out...the only thing that could have happened which is known to happen with some dell laptops is the main board warped from heat causing bad contact with the gpu or cpu....thus creating the high temps you see....which if that was the case you are out of luck unless you want to replace the main board but it would prolly cost more than a new laptop
  14. Thank toy for ur time and reply guys its realy been a great help , my laptop performance is improved a bit thx to u guys , and as u said it might be mother board problem coz i tried every thing else , once again thx for all ur help its realy been helpfull.....
