G73JH overheat and fans' noise

Hey,

After few years with the amazing G73JH, it's been weeks that its fans are playing some terrible music.
With no much load (matlab, cubase, chrome, office) the CPU's temp is around 90-100C (Everest) and the GPU's 70 (GPU-Z).
I kept cleaning them once in a while, but at some point it just didn't help.
I reached them through removing the keyboard and more, and clearly the GPU's fan made far more noise than the CPU's (which was noisy too), even when running the BIOS only (removed the HDDs)..
Did that happen to anyone else? should I replace the fans? or is that something else?

Thanks in advance.

P.S.
Temps given while running with a Zalman NC3000S.

 

In Bios the cpu is usually fully loaded (or at least has all cpu power saving features disabled), which causes some heat.
But your CPU is getting really hot, if you still have warranty I'd suggest you to replace the fans, or even get a professional "repaste" of the CPU and GPU. Search here in the forum for some possible issues with that though.

 

Sounds like the paste isn't doing a good job transferring the heat from the cpu die to the heatsink, so that may be one of your problems. Also if you have some sort of noise coming from the fan then it's time to take it apart and test them. To test the fan you have to take it apart and then feel for resistance. The fan should spin a bit and get some sort of magnetic resistance stopping it from spinning freely. It's hard to explain but if you feel a lot of resistance or hear a high pitched whine coming from the fan then it's time to replace the fan. Most laptop fans will come apart so you can take some graphite lubricant and apply it inside the fan. You don't want to use anything other than the graphite lubricant (wd 40 or white lithium grease will cause problems). You can use contact cleaner to clean it but it won't lubricate it at all.

Here's the graphite lubricant you want.
Shop The Hillman Group Graphite Powdered Lubricant at Lowes.com

If you have a lot of wobble in the fan then it's time to replace it, though with the laptop being newer i wouldn't think they need to be replaced yet.

If you want professional help you can pm me and i'll help you any way i can.

Good luck

 

Dust build up most likely. You really need to get inside to have a look but the more dust blocking the rads at the rear the harder the fans have to work. Could also be clogging up the fan. A common quick fix is compressed air in the rear vents a few quick blasts should cause a plummet of dust to come out, if so that is your problem. Otherwise get your hands dirty get inside.

If it is thermal compound related it could easily be degregation of the stock TIM which was always very poor after a good year or 2 of use or poor contact. ICD was always a winner with these models because it filled the poor gap left by bad workmanship from the cooling design.
