I'm worried about my Core i7 4700MQ

Hi guys i just wanna ask some quick question about my CPU and GPU temp.
i'm using tips from mr Fox to monitoring my CPU and GPU temps -->
http://forum.notebookreview.com/ali...mperatures-game-benchmark-screen-display.html

after that i run Crysis 3 on it for 1/2 hours.

and here is what i got :

- CPU Temp : Constant at 87 Celcius, the max temp = 90 Celcius
- GPU Temp : Constant at 77 Celcius, the max temp = 80 Celcius

and i also use HW Monitor to monitoring the temp



as you can see from the picture. 90 Celcius is very hot ! it's even can burn my hands !
i'm so worried about my CPU and also my GPU guys ... am i need to repaste my laptop or something else to make it cooler ?

your Advice is important for me

 

You would be amazed at how many Haswell laptops (I'm pointing at you HP Envy 15t, ASUS N550, MSI GE40, Lenovo Y510p) actually DO get temps similar to these ones, but judging by your previous posts you seem to have a quad-core CPU and twin GDDR5 755M's in a 14 inch laptop chassis, so these temps seem normal enough for such a laptop. Be warned that at 90°C your laptop will most likely throttle down to 2.4ghz. There are 5 possible ways you can lower your temps, from safest to most dangerous:

- Lower your game settings (less load)
- Invest into a good cooling pad (costs money)
- Lower your CPU multipliers (this might hamper performance but in my experiences it's pretty insignificant)
- Undervolt your CPU (might affect stability)
- Repaste your system (may void your warranty)

 

How about repaste it at the Sevice Center ?

and i got amazed how crysis 3 increase my temp up to 90 celcius just in 1/2 hours lol

btw thx for you reply ... i almost thought my laptop got a fail paste from the factory

 

Well it's know that Lenovo employees do not thouroughly paste their laptops, then again the same thing applies to HP and MSI gaming laptops as well. However since most people buy their gaming PC's off resellers, they often pick the custom repaste, which almost guarantees them a nice quality job of pasting their whole laptop.

Crysis is an extremely intensive game, and like i said, you are running lots of hardware in a small package, especially with that second GPU.

 

Usually the problem is far too much paste.

 

This is the core temperature not the case temperature which should be a fair bit less so unlikely you'll burn your hands. Unfortunately Haswell does run hot, I remember the days when people got concerned when core temps went over 70C lol.

The 4700 standard temperature throttling activates at 100C but there is an offset register to activate lower than that. On my 4700 it's set to 3 so TCC happens at 97C. ACPI may throttle at lower temps than that but that will be dependent on your BIOS.

Other than repasting try some undervolting with XTU which you can do without opening up the laptop.

 

when was the last time you cleaned the vents and fans out with compressed air. this is the main cause for raised temps and a good clean out has been reported to lower temps down 10c.

BUT crysis 3 is a demanding game and those temps are round about normal. raising the back of the lappy of the bench can help 1-2c and every little helps. also ambient room temps are a factor. if its summer where you are then that will raise them even more.

lots more monitoring tools can be found in my sig below.

 

repaste the laptop and be careful if there is kind of a sticker or s.th to prevent opening, use AC5 and get a cooling pad and you will be okey, else put the CPU max state @ 99% (this will deactivate the turbo) and you will have MUCH lower temps, or use a modded bios to deactivate HT you will win 5° avg per core

 

Also try using Hwinfo program to run fans at full speed when you game manually. Many laptops support this program and it is mighty useful in keeping temps down! Sounds silly that you have to deactivate turbo and HT on your CPU. May as well put an i5 inside lol. Sort you cooling and you are good to go.

 

i bought my laptop 4 months ago and i think it's not dirty enough to make this high temps
and also thx for your reply and now i'm go around in your sig

i think so ... maybe repaste will help much but it will void my warranty pfft ... it's so hard to decide.
and the temp that i post above is the CPU temp after i put the CPU MAX state @ 99% aka the turbo is disabled ,,, never touch 3.4 ghz ... only go around above 2 ghz

i remember with the turbo enabled ... my CPU max temp REACH 99 CELCIUS !!! it's alomost die i think

 

You would be surprised. I clean mine every couple months, those fans suck in a lot of air which unless you live in an Intel clean room, a lot of dust too. And no manufacturer ever does paste properly and they usually use lowest quality paste. There hasn't been a laptop that I have repasted that hasn't improved at least a few deg C.

On the other hand if this IS the 14 inch Lenovo, then those temps are fairly normal, but a good repaste and compressed air to the vents can't hurt. I really don't believe Lenovo voids warranty for repasting, although I could be wrong. But unless there's a "do not remove or void warranty" sticker they will be none the wiser.

In my 13" Clevo it can reach 99C in certain circumstances.

You do have options though:

- use Intel XTU (free Intel software) to clock your CPU lower for games that heat up temps quite a bit
- limit FPS using nVidiaInspector, run the game, if it runs at 50-60FPS try to limit it to 50FPS and you will see GPU temps drop by 5-10C
- repaste and use compressed air in the vents. Cheap, quick, and simple, and 99% of the time fixes the issue

 

any recomendation the best product for repaste ?

 

I use IC Diamond, personally. Just be sure to clean the CPU (and GPU if you need to do that too) of the old paste really well using highest % alcohol you can find (90%+ preferably).

 

i never repaste CPU before and i have no experience ... i hope this will be sucessfull
any tips and trick for me ?

 

as you mentioned voiding warranty earlier i would check with your supplier first as if there are stickers on the cpu/gpu removing these to repaste can also void the warranty.

at least with our clevo laptops they are user upgradable.

here is a walkthrough of pasting http://forum.notebookreview.com/sag...e-guide-upgrading-thermal-paste-your-own.html


this is an idea of the various ways to apply thermal paste

 

You can repaste the 2nd GPU, Upgrade the SDD/HDD/WiFi/RAM/ODD Bay without voiding the warranty, but gaining access to the main CPU/GPU requires breaking the warranty seal. Oddly enough, a guy took his Lenovo and did a full repaste+screen removal, and still managed to get his laptop repaired by Lenovo.

 

If your running 24x with those temps somethings not right. Be aware that with Haswell using 99% does not guarantee non turbo mode, best to confirm clock speed.

 

this is my CPU Clock when i put the MAX state @ 99%



the clock speed if the CPU MAX state @100% is 3.2 - 3.3 GHZ

are you sure 99% does not guarantee non turbo mode ?

 

Yes . Did I really need to answer this?

 

should i reduce it lower that 99 % like 85% or 80%?
i hope i will not get loss performance with 85%

 

No, you should fix your heating problem so you can get the performance you paid for.

 

OMG this a super helpful video thanks! I had just repasted the CPU/GPU's of 2 HP laptops I bought for a friends children which were running at stupidly high temps and one even shut off when playing games (thou I also bought an ASUS which was quite cool and didn't have the same issues so I am figuring HP laptops are not well built as my networks teacher told us and my own experience), I used Arctic Silver 3 & Ceramique in a spread method along with spreading the heatsink initially then wiping that off but it didn't make any difference in one (AS3), actually idle increased by 5c but the max was slightly less (I did it twice due to this and had the same result), and did make about 5-10c in the other (Ceramique). I used Prime95 to test.

I am just playing Trine at max settings on my Gigabyte P25W with an i7-4700MQ & Nvidia 770M and I noticed the temps were getting into the 80's then came across this thread. I can't repaste the CPU as it's meant to have a label on it but I will do the GPU and see if that helps. I notice in the video that AS3 is not a very good spreader and wondered how Ceramique was as it's meant to be superior I think. Does anyone know if that is silicon based or ceramic (as the name suggests?).
