Hello, I bought used T410s two weeks ago and it gets really hot. Temperature of CPU without tpfancontrol was about 85C when only Chrome was open it wasn't stressed. With tpfancontrol on "smart mode" it low to 70-73C. It's i5 520M version, please let me know is that temperature ok and what i suppose to do if not? Sorry for my english cheers

That machine is about 5 years old by now.
Open it up to clean the fan and replace the thermal paste between fan and CPU.
Preferred paste: AS5 = Arctic Silver 5
Instructions for thermal paste: http://www.arcticsilver.com/pdf/appmeth ... d_v1.1.pdf

Ok thanks for reply, what do I need to replace the thermal paste? I'm guessing i need something to remove the old one. Arctic Silver 5 is quite expensive anything cheaper will be good enough? As you said it's 5 years old now and I do not want invest money to this and thanks for HMM link

Cleaning the fan may be enough to lower the temps (if a dust clogged fan is the culprit). Take off the keyboard + palmrest, hold the fan down, hit the area with a few hits of compressed air, and test the results. If its not enough, then new thermal paste is probably needed.

The problem is that the seller told me it was cleaned inside so I think the thermal paste is the problem also it is version with ssd 80gb intel drive so maybe it is the problem. I have read many posts on forum about overheating T410s so it's problem with this model.

Don't take a word of a seller as a gospel unless you know them personally...

A system with an SSD should run cooler, if anything. Having said that, 1st generation Core i (Arrandale) CPUs tend to run on the warmer side of the spectrum.

If you want to spend as little money as possible:
1. remove the fan and heat sink
2. clean both
3. take the machine, unassembled(!), into a dirty looking computer repair shop and ask them to put a rice-sized drop of lepszy thermal paste on the CPU.

I am not sure how much thermal paste costs in Poland, but if AS5 is too expensive, there is also Tuniq Tx-4 which performs very well.

You don't need the bigger one, the 3.5g syringe is more than enough ("A 3.5 gram syringe contains enough compound to cover at least 15 to 25 small CPU cores, or 6 to 10 large CPU cores, or 2 to 5 heat plates"), and this one costs ~25 zł (checked on allegro.pl). Anyway, instead of AS5 I'd go with Thermal Grizzly Kryonaut (better performance), for about the same price, but smaller quantity (1g).

The thermal compounds from Lenovo and other OEM's were never top quality IMO. For proper cooling you will need to replace the paste as other forum fellows had pointed above.

For this particular model you will need to do quite a lot of disassembling , but if you follow the HMM step by step it shouldn't be a problem.

That's indeed a good one! Other brands I can recommend are Artic Cooling MX2/MX4 and Noctua NT-H1. Don't go for a cheap no-name brand, although your T410s is 5 years young, maxed to 8GB and with a nice SSD it will serve you well for some years to come (except for gaming maybe)
