Changing to P8600 or Staying with T9600?

Hi. I have a question about the P8600 and the T9600.

I know about the cache difference, clock difference, and the TDP difference between the two. I currently have HP's dv4t with the T9600 (2.8GHz, 6MB L2 cache, 35W)

I'm considering to exchange my current unit with another one that has P8600.
I hope to see the P9500 as an option, but HP is certainly not offering it.
I realized that the T9600 is too much for me as I don't use any CPU-intensive applications except some video encoding. Actually, the reason I'm not satisfied with this laptop is not the T9600 but the hard drive temperature. Because there aren't many dv4t users right now, I can't figure out whether my hard drive is a defect or my whole computer is a defect. Because of the hard drive temperature, I'm considering to return my dv4t. Anyway,,,

Here are some questions...

1. Do you know what an idle temperature for the P8600 is?
The idle temperature of the T9600 is about mid 40's.
2. It is clear that the T9600 is much faster than the P8600 in benchmarks. But, would there be any
difference in daily use?
3. Would video encoding with the P8600 take much more time than with
the T9600?

 

1. nope
2. not probably. u would have to stress it real bad.
3. i doubt it. small amounts maybe a few minutes more

 

Then, do you mean that I won't notice a huge difference between the two?

Is there anybody who has a notebook with the P8600 or other P series CPUs?
Please give me your idle CPU temperatures. That would be very helpful for me

 

What HDD temps are you getting? What HDD do you have? If you are switching to a notebook with the same cooling solution could still face same problem. Poorly designed cooling solution lower TDP might work but a desperate attempt at dealing with a fundamental flaw that I suspect could continue to plague you.

1)No
2)No
3)14% less clocks throw in a high est 8% for L2 difference 22% I would guess about 20% give or take max. What takes 8 minutes T9600 takes more like 10 minutes T8600 video encoding.

There are other ways to address heat issues but I don't think one should have to be playing with these on a new computer. Bad cooling leads to premature hardware failure. Sadly many times when just out of warranty.

 

I have a 160-GB Hitachi hard drive. It stays at temperatures from 48 degrees Celsius to 53 degrees Celsius. The hard drive temperature was about 29 degrees Celsius when i turned on the notebook, but it reached about 50 degrees Celsius within 30 minutes. I'm trying to find whether other dv4t users have the same problem, but mine looks the worst among the few who have the dv4t. The few who have the dv4t said their hard drive temperatures remained under 50 degrees Celsius. I think I won't need the t9600 much, and the temperature advantage of the P series processors is attracting me.

My T9600 works just fine, but the problem lies on the hard drive. The hard drive runs hotter than the CPU or the GPU!!!!

My goal is to get a new dv4t with the P8600 and to figure out whether it has the same hard drive overheating issue. If it has, I'll buy a notebook cooler.

But, I want to know what tempratures of the P8600 are idle.

 

PlanetEarth I understand your concerns and thinking on it. I will elaborate but first. I don't know the average idle of P8600 or else I would tell you.

But knowing others idle P8600 temps while of some use is not of much use. The CPU is in an enclosure and temps are the result of a system.

Your HDD temps are with in specs 55C is the highest on most. I agree higher than many would want.

Are you going to trade in for same system with different CPU? If so not good. You state that the CPU and GPU temps are fine? It is the HDD. If your HDD gets to the temps you have said when CPU is at the temps you have said at light usage then I can almost guarantee a CPU swap will do nothing to solve your issue.

Cooling system is poorly designed? It looks as if the active component is working fine, fan or fans along with the heatsink's passive heat radiation. The problem looks like passive convection and radiation cooling is not adequate for HDD.

Reduction of heat in anything close to a 1:1 ratio is unlikely. I would suspect much much lower.

I don't like telling you what you don't want to hear but I want you to be aware of the reality.

Your cooling solution from what you say has no problem dissipating heat in two areas, CPU and GPU. But can't do it for HDD even in non stressful use. Pretend your heat is water, your CPU and GPU water is in one bucket the HDD water is in another. Well you switch to a P8600 so you dump water from the 1st bucket? What affect does that have on the second bucket? Zero, my example is extreme but it in my opinion has validity describing my concern of your situation and why changing CPU's might not address the problem.

Very sorry I can not say positive things. And I could be wrong but right now have real concerns about your proposed solution.

 

Well, I know... The reason I want to change the CPU is to save some money, not to solve the hard drive overheating problem. Moreover, I think the T9600 is too much for me, and I think it is not worth the price that I paid as I won't use much of its processor power.

At the same time, there is a chance of getting a better hard drive that does not overheat as the current one does. I'm not saying that exchanging will solve the hard drive problem, but I want to change the CPU to the P8600.

I know the the CPU and GPU temperatures are totally different from the hard drive temperature.....

I really appreciate your help and advice

 

I agree with you 100% then and think it is a very good path to take. I had the priorities out of order. Also remember up to 55C is well, within specs. And the P8600 will not raise temps so anything you do get is bonus. Cash back is always a good thing.

 

Yes.... Cash back is always a good thing

Thank you for your advice!

By the way, it seems like there are not many with the P8600...
