High GPU temps normal for c90s?

Everytime I play a game my temps soar up to 105C sometimes. Should i be concerned because there seem to be no issues with my 256 mb gdr3 card. It works perfect no slow downs or anything. I just dont feel comfterable knowing my gpu can make water boil...

 

yeah it's normal, it's the max you should be hitting though.

I'd suggest underclocking if you do not need all of the card's power (because the CPU isn't strained so the fans aren't kicking.

I play guild wars at 200/250 so it keeps my gpu at 88C

 

Acctually to tell you the truth there is something weird about this card... Right underneath the mouse pad is a is a small vent. One time I was just messing around and felt a small drag underneath coming from it when i put my hand under it. So I let the vent hang out the edge of my table. The results were crazy! I have my gpu set to 550/823 with max tempreatures reaching 105c sometimes. I play company of heros everything full at 1200x960 with those clock speeds and a temp of 94c as a high. Try to put the vent of the edge of the table... youll notice a difference. The funny part is i seem to be getting the same temperatures with stock speeds sometimes going to 103c. So why not just overclock it then anyways and take the extra 2c.

 

klok, are you using a cooling pad? they are pretty much needed these days for gaming notebooks. I dropped my temps 5 degrees centigrade immediately by using one.

 

Seems like Asus has some real work to do in the cooling department.

 

no cooling pad... im thinking about drilling holes and getting one... im more frustrated with updating drivers then anything right now. The temperatures i guess are normal... do you have any advice on which cooling pad to get... maybe a link

The best one I've heard of but also the most expensive. There are others that are half the price or less but they don't cool as much, are generally louder, or just don't last long. This is the best one people have recommended to me.

 

Many people use the Zalman NC-1000. I have a Lapcool2 which works great, but I've been using a Belkin (Wave shaped) that works just as good and packs away easy to take with me (usb powered).

EDIT: The Belkin (29bux) is single fan, but the shape I think is great for the C90s and it works pretty great. Wish I had it in Black though.

 

does it suck air or blow air at the computer?

 

The Belkin blows air AT the computer. So does the Lapcool2 and Zalman. Most do, but you have to watch it.

 

I would not be comfortable with over 100c I would call that my absolute max.

As for the cooling pad I have the Zalmans and I cant agree that it cools the best, but I can agree its probably the best quality and definitly the most silent.

The fan design is super silent but the CFM (air movement) is not as high as other coolers may be. So if you want only max temp changes you may want to look for something else.

I really wanted to try the new coolermaster notepal infinity but its not avalible here in the states yet and I dont want to pay for the expensive overseas shiping.

The c90 fits on the zalmans pretty good, if I slide it all the way forward (twords me) untill the rubber feet are on the edge, it puts about 90% of the vents over the air holes, also it matches great with the black and gives that nice tilt to type on.

 

IMO, the rubber feet on the C90S are too short. If you prop up the notebook a half inch or so, you'll notice a big difference in temp when playing games.

 

I agree with Shadi, any kind of airspace you can provide the c90 underneath with make a decent difference without the use of Mods/cooling pads. Although the latter will most likely give the best cooling.

 

That's what I like about this weird Belkin cooler, that wave shape gives it much airspace between the fan and notebook bottom. It seems to pay off for a single fanned unit.

 

if your CPU and GPU share same cooling pipe, it would be difficult to get a comfortable temperature. this kind of thermal design is not optimal for minimizing thermal resistance and hence is not a good thermal design.

 

There're not using the same pipe.

IMO, the fan for the GPU should be independant from the other 3 and be activated with the GPU temp. That would help it alot.


BTW: I found a fix playing guild wars, I turn off AA and UC the core @200mhz. It stays under 90

 

Correct, different heat pipe and different radiator.

 

The turbo engine in the back has 4 fans, 3 of them and 3/4ths of the vents go to the cpu. One of them and 1/4th of the vents go to the gpu.

I cant belive the cpu is that much hotter than the gpu. I was very supprised when I saw this. In my opinion 1 fan and one little piece of heat sink for the gpu is not nearly enough adn they should have made the turbo engine just abit larger to add atleast one more fan and more cooling area for the gpu then it would have been working much better on its own.

Plus it would have allowed for hotter more powerfull video cards to be used in the future.

 

it seems you have desktop cpu, that's quite tough for laptop thermal structure.

 

But next gen will be 65nm or maybe even 45nm so heat *should* be less.

But yeah I agree, there could have had more cooling on the GPU for sure.


Mine rarely goes over 65C, even under load. Designed temp on my E4500 ( is 73.3. I think those with the E4300/4400 might have problems though, since those are designed for 62-64C

 

Thing is though, the desktop cpu has no heat problem. Myself, I don't have a heat with the gpu either...a little on the warm side, but nothing to lose any sleep over

 

E6600 is 65W TDP while T7xxx is only 35W, huge difference... run TAT for a while and see your CPU max temps...

 

Yes, but it's not a problem. This has been hashed and rehashed. Actually, the massive cooling system works pretty well, however it seems more should have been allocated to the gpu.

 

After I replaced my e6700 with a e6600 my temps went way down. I sit at a low 60s high 50's idle and in overclock mode hit like a aboslute max of 75c and thats not bad at all for a cpu.

The problem is my new cpu runs so cool the gpu runs hotter because the fans dont like to come on.

Looks like my first cpu and gpu both had issues with running hotter than normal. I just put the replacement 512mb card in and put some cheap evercool tim on there and while I have not let it sit long enough yet Its under 50c idle (cooling pad tho) Its running 3dmark stock clocks 169.01 drivers right now with nmonitor logging temps every 5 seconds. Going to see what max load temp was, then repeat at 500/500 clocks.

Im thinking the 512mb card is good enough for me it runs pretty cool and confident at 500/500 wich puts it right next to the power of the 256mb GDDR3 card stock. The GDDR3 card can go another 700 points higher for a score of 4700 but its pretty hot and the driver issue bugs me.

Infact just got done with the first run.

stock clocks 475/400 169.01 3gb ram 3400 3dmark.

Max load temp was.... 72c ! ^^

 

Exactly! Like you said I think, it's better to run in Overclock mode because the fans drop the gpu temp at least 5 degrees or so I've noticed anyway. BTW, can you set turbogear to run in OC mode at startup? I haven't seen where.

 

Yep cpu runs hotter so fans come on more, plus I think overclock mode nativly makes the fans run abit faster.

Only competing issue with this is that me and forerunner both found that a lower cpu mode like normal or game mode allowed us to overclock the gpu more.

I tested last night to confirm and even found that it is not a heat issue, for some reason overclock mode limits the overclock. I cant get past 500 core in overclock mode but in normal mode I was stable all the way up to 575 core.

But since the cpu is running slower, my 3dmark score didnt really go up with the faster gpu...

I did the overclock mode 500/500 run and got like 3970 3dmark and a max load temp on the gpu of 78c. I think thats where I want to be for a 24/7 speed/temp.

The GDDR3 was pulling 4700 points in overclock mode with 500/800 but I think the temps were close to 90c (wich is not horrible but I much prefer 78c ^^ )

I have one last test and that is installing the turbogear enhanced vga drivers and running the 500/500 test again to see if scores go up. Because they went down when I uninstalled it with the GDDR3 card.

So I want to see if its like a magic program or not.

 

Turbo gear did nothing for the 512mb card just raised the stock clocks up some like a amature auto overclock (good tho since it works with all drivers even those that dont allow overclocking) for some reason it effected the GDDR3 card differently tho.

Anways I love the new 169.01 drivers they allow you to overclock and have the downclocking function working right.

Cpu idles at super low 50's and the gpu is in the high 50's (cooling pad on) but that makes the c90 feel like a regular laptop now not a toaster oven.
