Y510p Ultrabay GPU at 97C idle temp

Hi!

I have a new Y510p with GT750 SLI. The CPU and first GPU have really good temps (40c idle, up to 70C when playing games)

The ultrabay card however, goes all the way to 97C over the course of a few minutes, with little to no load (Only Chrome Open)

I want to know if i should open the ultrabay and repaste it, or if it's better to replace it under warranty.

 

As much as it pains me to say it, ultrabay cards DO run that hot, and your temps probably will not improve much if you get a replacement. I suggest repasting the Ultrabay.

 

I was afraid that might be the case. I'll repaste and post updates.

 

That is the first thing I plan on doing when I receive my new one tonight. Going to repaste the bay, then see how the main runs. If that is anything over 80-81 C, it is all getting repasted too.

 

You can repaste all you want but it's not gonna be anywhere close to running below 80C at full load (100% CPU & 100% GPU) unless you do some mods and/or undervolt, or you live in Antarctica.

 

Oh yea? Running 76C as the MAX temp under Ultra settings of BF4. That is the Ultrabay card. I repasted it as soon as I took it out of the box.

The CPU is running at 75C as the MAX and I did not repaste it. Now, I might do it just to do it, but as of now, it runs great.

I can tell you that the cooling pad I purchased, drops the Ultrabay temp even more. As much as 10C more.

 

How long did you play BF4 for before noting those temperatures?

BF4 is not simultaneous 100% CPU and GPU load. Try running Unigine Heaven and Linpack at the same time for an extended period, then see what temps you get.

Throttling and lack of Turbo Boost is a well-known issue with this laptop out of the box. Try using ThrottleStop for the CPU when gaming and benchmarking, otherwise it's not running at full speed. I guarantee your temps will be higher, perhaps much higher.

What magical cooling pad do you speak of?

 

I am using a Cooler Master SF-17, works real well.

I will try the load tester, I played BF4 for about 30 minutes. The only issue I am having is a black screen on boot sometimes. It just sits there and I have to do a hard restart multiple times. Getting a bit upset.

 

Oh that mammoth thing.

 

lol, yea it is decent size, but very quite and it works better than any I have tried.

The only downside to it is the connection cable. It connects on the right hand side and sticks out to the external mouse, which is a bit annoying, but not too bad.

Getting ready to try the burn in test you suggested. I will post results.

 

Make sure you're using ThrottleStop too.

 

Well.......

Ok, so played BF4 again today, just now actually. The CPU and main GPU are running perfect and the MAX temperatures are 78C CPU and 80C GPU.

NOW, here is the problem. The Ultrabay just hit 97C and my game shut off and it threw an Nvidia error. I am a bit pissed.

This was on the cooling pad too. I don't see how in the hell that the main GPU and CPU can stay that cool and then that runs that hot. I repasted that with the best paste you can get too. Really strange....... From what else I read, there really isn't a way to get them lower. So let's cut the BS. The ultrabay card is absolute garbage and you are wasting your time with SLI, am I right?

 

What about your power source. Is it the version with 170W? Perhaps you have instable current or voltage for the second GPU.

 

SLI in itself is not garbage, Ultrabay as a conception is brilliant.
But the cooling of ultrabay, well that is garbage.

Things you can do: ( warranty unfriendly solutions)

- Use the laptop with removed bottom plate, check temps. This one actually warranty friendly.
If you have lower temps, then further ones is a way to go:
- You can cut the base chassis , and bottom plate to have bigger hole for ultrabay, to suck in fresh air.

- You can remove dust filter, so ultrabay can get more air.
- You can modify mounting mechanism to get more pressure on chip.
- You can modify ultrabay heatsink with added copper shims, to act as a "heat capacitor", full load temps will be the same, but it will reach that slower, cooldown is slower too.
- You can change fan to higher speed one( finding a replacement one is no luck so far), or cut in a bigger fan, this one is actually very hard to do in such thin chassis.

 

I do have the 170W 20V Power Supply.

I agree with most of the options that you have stated as a work around. I don't agree with putting a lot of pressure on the chip itself as that can only lead to damaging the chip.

With that said, I have a new replacement Ultrabay 755M coming tomorrow (Friday) and I am going to use it right out of the box and see how it does.

The stock one, I took apart as soon as I got it and repasted it with IC Diamond 24 Carat. It did nothing for it as it still overheats just as stated above.

However, the laptop itself, I have not repasted in anyway, and the CPU and GPU are running at fine temps. So I haven't decided on whether or not I will keep this laptop as a whole or return it. Tomorrow will tell me a lot when I get the Ultrabay GPU and see how that works. I am hoping I have a defective Ultrabay and the replacement is going to work like it should.

I already have an RMA that is almost a week old and shipping label, so I need to make the decision soon. I really, really love this laptop. I like the look, the feel, the overall ergonomics, just everything. So I am really hoping that it works and I can keep it.

 

Using higher pressure means thinner layer of thermal paste, better heat conduction. Considering that, thermal pads on memory has to be pushed as well. strengthening the mounting mechanism is a good way to go.

I would not expect anything from replacement, as those workarounds are countering design flaws. Replacement ultrabay wont change chassis, intake of ultrabay fan, and so on...
Slight chance of getting better, flatter heatsink, with proper amount of thermal paste. But the final, full load temps will be the same.

 

I am running a SLI 750M by default (170W power source) since 2 weeks (german edition with 256GB SSD).
I can also see nearly 90°C for the second GPU. 80°C for the main. CPU is 20% load. I am using Unigine Heaven 4 Benchmark.
I do not have BF4 to test. Can you test your temps with this freeware benchmark?

 

Dota 2 runs around 90 degrees on ultra bay and the main cpu/gpu are "Okay". This is w/o a laptop cooler.
With laptop cooler it drops 5 degrees respectively. Only thing left to do is possibly cut the laptop chassis itself to allow more air into the fans...but Im not sure what tool to use.
