Would i need a repaste for g73jh?

gpu temperature seems absolutely fine but cpu temperature is getting on my nerves. Idle temperature goes down to 50~60degrees when i change my battery settings to battery saving or quiet office setting but when it comes to high performance setting, cpu temperature goes up to around 70 degrees even when I don't do anything. Funnier thing is that I get the same temperature even when I am playing games such as crysis, metro 2033, or skyrim. I am really nervous because I used to get so much lag due to the high cpu temperature. For time being there's no lag but I wanted to know if I would be needing a repaste.

 

What are your ambient temps like?

1. Use compressed air to clean out the rear vents. Focusing on the left vent which is the CPU.

2. Make sure you dont have any software that is stessing the CPU unecessarily which could be the reason why it is using resources and raising the temps.

3. If your compressed air application fails to work you could consider an RMA (within warranty) or go for a repaste yourself which will most likely resolve your heating problem if it is not related to dust or ambient temperature. Poor application of thermal compound is sometimes a common problem but dust blocking the rear vents is most common of all, 95% of the time people see a 5-20oC temperature change by removing the dust blocking the radiators which allow air to flow through in order to remove the heat from the heatsink.

 

What are your max temps? Cause 70s Celsius is good

 

in ambient temp of 74degree fahrenheit, max goes up to 76 degree celsius.. and it also happens when i am not stressing the CPU at all.

 

Yeah, 70-80 degrees is really not bad at all for a Radeon 5870... I just had my laptop die 1 month before my warranty was up, and I just got it back.

The video card had died and been replaced and they also replaced the motherboard, and my Furmark stress test temps rise to about 70-71 degrees after 5 minutes or so. This is with an obviously new paste job, so if you're seeing 75-80 you're fine. I'd only really worry if you were pushing 100 which many people have reported in the past. Frankly at those temps you could overclock reasonably without your temps getting too high (obviously you'd want to run Furmark to check your temps at higher clocks), but anything under 90-95 at full load should not cause an issue.

 

God must be on your side with that one, perfect timing and a new MOBO too looks like a keeper. If you haven't already the 920XM and an SSD are calling your name
