Hi to all, Thanks for keep this forum running . I have a question about Toshiba Satellite L505 v10 temperatures. The system has a T6600 Core 2 Duo and ATI Mobility Radeon HD 4570. I’m receive this laptop used and I don’t know what really temperatures can reach with normal use. I’m changing the fan with a new one fan but lower amps (because the seller didn’t have other fan), because the other one is noisy I think that is broken. This laptop has one central cooler for CPU and GPU. I’m cleaning the cooler. The GPU thermal pad is melted from heat and I’m planning to replace the thermal pad with thermal paste. I’m getting prolimatech pk2. I also removed the VRAM thermal pads and I’m inserting thin pads to reduce the gap between GPU and cooler. I’m also used one round pool to keep the cooler at it position. After all that I’m get temperature mesuremets as follows: Room temperature is 26 CelsiusIdle cpu : 47 CelsiusIdle Gpu : 53 Celsius Youtube full hd video playback for 15 minutes: GPU: 68 Celsius maxCPU: 55 Celsius max I don’t know if these temperatures are correct for this laptop. I’m afraid to stress it out more because I don’t know if these temperatures are safe to run a benchmark on it… I don’t want to burn the CPU or GPU. I use hw monitor and gpu-z to measure After 5 minutes idle the laptop come back to 55 Celsius (GPU) and 51 Celcius (CPU). I think this temperatures must be lower. Are these temperatures safe? Must I buy other thermal pad to reinsert thermal pad on the laptop? Any one with similar configuration can confirm that get this temperatures?
This will depend on exactly what processor you have. Post your numbers of the processor so we can narrow it down. For your CPU these numbers are the sustainable temperatures, you can get higher number for a brief time but not sustainable over long periods: Northwood (130nm): ~73.4C Prescott/Prescott 2M (90nm): ~66.6C Conroe/Allendale (65nm): ~60.1C-62.4C for your CPU For the GPU this will be around 71C but again it will depend on the actual processor. If you can, let us know those numbers as well. For now, your temps are definitely acceptable.
Generally you want to replace pads as the gap between the heat sink and the top of the chip maybe to great. Here’s one source: Artic Thermal Pad As an alternative you can use a gapping paste like K5 Pro I have found these gapping types of paste’s don’t last as long as the pads in their cooling effectiveness. CPU & GPU’s which had paste on them should have paste put back on. Here’s a good guide on what to look for: Thermal Compound Guide. I’ve personally found Arctic Silver holds up well. But, to be truthful here any good quality thermal paste will do.
