T500 with T9900

My laptop seems to be throttling down when gaming. I am sure part of this has to do with the increase in ambient tempurature. I notice that with an ambient temperature is 26-28c my cpu is throttling during heavy gaming. Is 26-28c too hot for heavy gaming?
My as5 is only 6months old so it should be good. I'm sure i applied it correctly as all through winter to spring its been good except now when the ambient really starts to climb.

Ive been using throttlestop to avoid throttling during gaming.

 

28C is a ridiculously low temperature. Most software reads core 2 duo temps wrong since they dont know the tjmax offset for every processor. This wasnt really an issue in the past or current processors. Coretemp and real temp are usually good about it but most other apps can be adjusted Hwmonitor just edit the ini file.

 

What is your ambient room temperature? That's pretty good for a T9900, that is the fastest Penryn Core 2 Duo, should be hotter than that. Also realize that all temperature reading programs should be taken with a grain of salt, your real temperatures should be the current read out + ~10C.

 

Sorry i wasnt clear. 26-28c is my ambient and this is causing my cpu to throttle. Speedfan reports my cores at 90/85 and 82/76 when undervolted. Im just wondering if this is an indication to repaste. Can the t500 chasis really handle the tdp of a t9900 in warm weather? My unit was shipped with a p8600.

 

Ah alright read your original post wrong. Yeah that's pretty bad? Was it throttling at first or it out of the blue has been throttling? Maybe you are due to a repaste and laptop cleaning?

 

If that is working for you then carry on. When under volted, your CPU temperatures are fine if SpeedFan is reporting it correctly. The correct TJMax for a T9900 is 105C.

As long as your core temperatures are below that number then you are running your CPU within the Intel specification. ThrottleStop can not prevent the Intel designed thermal throttling when the CPU gets up to this temperature so you don't have to worry that ThrottleStop is going to allow your CPU to run beyond the Intel temperature spec.

It might be the GPU that is over heating and triggering throttling. Some manufacturers use GPU temperature data to throttle the CPU. Try running GPU-Z to log your GPU's performance.

 

I will download gpuz and see what my 3650 is producing. The hsf is one unit and it cools the cpu, gpu and north bridge.

 

while the CPU maybe fine at 105 degrees for a while, there is also the problem of heat soak on other components around it.

Also, running your CPU at high temperature will increase the effect of electromigration, which will shorten the life span of these CPU.

 

I'd definitely consider keeping it under 90C.
I wouldn't consider OC'ing your GPU for games; there's not enough headroom.

I'd definitely repaste. Also clean out the vents.

Do you set TPFC to fan level 64 during gaming?

 

I don't let speedfan or any other program control my fan speed. Its controlled by default. I'm going to re-paste tomorrow night. Hopefully it will improve. Hope its going to be a hot night (26-28C ambient temp).

 

I have a T400 and also put a T9900 cpu in there. I know it is not the same chassis but the two computers are meant for the same cpu.
With ambient room temperature at 26C the cpu reaches 74C.
My vents are clean I also used as5.
I also had worries like you that I might have not used the as5 correctly or something was wrong because my T9400 before would only reach like 48C or something. But like other people said the T9900 is the fasted and hottest cpu for that class.
Also when I have it in battery mode it is really cool.

P.S.
I have not tried to undervolt it

 

what method did you use for AS5? Thin and spread it out evenly on the cpu core\chipset\gpu?
Did you keep the GPU thermal pad?

 

For laptop CPU's, all you really need is a rain drop size of thermal paste. Use a old business card or credit card and spread it thin. I don't trust mounding it and pressing the heatsink on it. What I like to do is screw down the heatsink all the way and unscrew it and make sure it makes proper contact. AS5 and MX2 easily spreads, TIM like IC Diamond 7 spread like molasses.

Chipset I prefer to use ceramic based themal paste as silver/metal based conducts electricity. GPU really depends on your setup.

 

Will be doing a complete tear down, clean and repaste tonight.

 

Jesse>>what software are you using to max your cpu's temp? Also what software are you using to report your temps?

 

I'd use IntelBurnTest to stress the CPU, and HWmonitor to watch the temps; it offers all available sensors whereas most apps report the lower one (TPFC reports the other one).

 

repasted it earlier. cleaned the snot out of everything with alcohol. I gave it a bit extra AS5 and it works like a charm. Played some games and it has not throttled yet. CPU temp are much improved. Right now its 26C. I cant wait until its 29C in here and really put it to the test.

 

Well that's great to hear, keep us posted.

 

I did the thin spread and I did reused the gpu pad.
I dont use any software to max my cpu, I simply check HWMonitor (CPUID) when I feel my computer working hard, which is usually using heavy CAD or some rendering programs.

Its good to hear you redid it and getting better results. I might do the same

 

I removed the thermal pad and I found that I could press the hsf down a bit further (Cant remember if it was the northbridge o the GPU). Any how, to solve this gap, I wedged a small piece of folded paper so that it would help put more pressure down for better contact. I could post pictures if anyone wants a better look. This whole repasting and thoroughly cleaning the HSF took about 45minutes.

 

BTW, I think this would also apply to T61 and T60 users as the chasis is identicle.

 

If you have a T9900 and are using HWMonitor, look in the hwmonitorw.INI configuration file and make sure that it is using the correct TJ Max value for your CPU.

Edit the following line in the INI file if it needs to be corrected and then restart HWMonitor.

CPU_0_TJMAX=105.0

 

The T500 chassis is not identical to that of the T60 or the T61.

 

I thought it might be very similar because the external looks is very similar. It wasnt until the t510 before it was externally redesigned.

 

The design of the T500 was based on the 15.4 inch T60 and T61 machines. But there are changes on the T500 to make parts incompatible between the different machines.
You could interchange a lot of parts on the T60 and T61 15.4 inch machines.

 

After some intense gaming, my temps are:
85c/80c CPU
88c GPU

ambient temp 24C

 

this is about the maximum temperature i have seen in my T500 when used for gaming.

 

The real test would be with an ambient temperature of 28C. I'm afraid it will likely throttle again.

 

Yeesh, that's still hot. AS5 does have a bit of time for curing, but it will hardly make a difference (1-2C max). Perhaps time to downgrade that processor

 

Down grade? NEVERRRRR. lol.
I will just enable throttle stop when it gets real toasty.

 

when you switch to the integrated GPU, what is the maximum temp this machine gets to?

 

i cant play my demanding games with integrated graphics. Anyhow, its 28c here in my house and my temps are: 90/85c GPU91c

Toasty but hasnt throttled.
