Help regarding my XPS 1645

Hello everyone. I have an XPS 1645 with Core [email protected],6 gb ram,and ATI 5730 graphics card. Its normal temperatures hover around 60C and while playing games, it reaches 80-85C, sometimes even 90+.Also recently it has become unbearable to play any games on it, even NFS:MW after a few minutes starts lagging. Any suggestions.

 

I had this same machine a year back and just like you I faced overheating problems. Guessing by your ID I suppose you are from India and its really hot here (especially without AC).
So if you also have high ambient temperature, this results in high operating temperatures for this machine and temperatures of this laptop reaches a staggering 100c too. I think right now your thermal pads of CPU and GPU have lost contact with the heat sink (might have melted or so it seems) and thus these high temperatures.

Some people have noticed drop in temperatures by removing dust filters, blowing compressed air in the vents, cleaning the inside of the laptop (making it dust-free), buying a cooling pad and most importantly by doing a repasting job of the thermal compound. Let me know which road you are planning to take and we can decide accordingly.
Good Luck.

 

Undervolt the CPU if you can, it will greatly reduce the amount of heat generated and should prevent throttling. I have a XPS 1670 and with the 9 volt battery I can game without a cooler without issue. I was going to return the 1670 until I discovered undervolting and found I my 1670 was perfectly stable, and cooler, after doing so.

Here is a how to:

I dropped around 5C by removing the dust filters and repasting. Adding a cooling pad with fans will drop you even further.

Unfortunately you can't undervolt the Core i-series of (mobile) CPUs with software, and there are no BIOS options to undervolt, even with the 'unlocked' modded BIOSes for the 1645/1647.

Also, what is a XPS 1670?

 

Ya, which XPS 1670 are you talking about?

The ones I know are 1640, 1645 and 1647....and then they discontinued the SXPS series.

 

Sorry, I have a XPS 1640, not sure why 1670 stuck in my head, probably the "70" from the GPU. It has a HD Radeon 4670 and a Core2 Duo. Undervolts like a champ, stable as hell and never gets near throttling temp's.

 

The 1640 has a Core2Duo CPU, so the undervolting is possible, unlike with the Core i CPUs. With the Core i, they moved what used to be the northbridge chipset onto the CPU die, including the CPU voltage regulator, so it is not possible to control the CPU voltage the same way as you could with the older CPUs.

 

Well I have a 1647 or 1645. Its the one with the upgraded HD Radeon 57xx.

Yes overheating is a problem with this laptop when playing games on it. My suggestion is to get a laptop cooler. Its a couple dollars investment that pays off in the long run.

I have the NZXT Cryo for 15 inch. if you have a 9 cell battery in your xps studio it should align up to the back of the cooler and keep it stationary. Also the cooler aligns with the holes on the bottom of the laptop. Costs roughly $40.

This cooler will keep your laptop cruising below throttling temperatures. When i first got this cooler it could bring my laptop from over 100'C to under throttling temperatures in less than 20 seconds. Takes a bit longer now that the fans are weaker. But yea. GET A COOLER!!
