High Temps NP8677

You can't really blame Clevo though. These fans they use are stronger than Alienware fans and they can get ridiculously loud. I'm very sensitive to fan noise and when I compared the noise of my M17xR1 with the noise of my NP9377 I didn't think I could handle it but the temperature delta between auto fans an max fans on my 980Ms is a whopping 10-12C. At stock they hit 87C and throttle their core down from 1126MHz boost to around 1075MHz, sometimes lower, within about 10 minutes of a fully maxed out Heaven 4.0 run while they stop at 76 and 78C respectively even after an hour an maintain their full boost with max fans on. When the fans are on max though, you can literally hear them in a room down the hall. That kind of noise isn't acceptable to everyone so you have a choice

 

Thing is I could only compare sager with brands I had before. Non of them ever overheated. Talking about asus g73 I think and alianware. Mybe as you said its just this new procesors overheatin motherboard

 

What processors did you have before? These new chips run so hot that Intel intentionally sets them up to throttle by design at 95C. My 4940MX has a 3.1GHz base clock with a 3.8GHz 4 core turbo... Out of the box, my chip that cost me another 1K over the base 4700MQ this machine came with at the time, it runs 3.5-3.6GHz under a full core load, sometimes down to 3.4-3.5GHz. That's with a 57W TDP.

Turning up the TDP to 70W and raising the power limit from 71A to 105A lets me get a full 4 core 4GHz clock that will still power throttle down to 3.8GHz under a full load and raises the temps from 80s with max fans to around 93C. That's even with IC Diamond AND a -80mv undervolt. So yes, these chips are hot as the sun and it's by design.

 

alianware was Intel Core i7-4800MQ. Asus I think it was Intel Core i7-3610QM, and now sager Intel Core i7 6700HQ. Bigest problem I see now is motherboard reaching 85-90c. Never saw that before

 

First off switch to HWiNFO64 for monitoring sensors so you can find out what exactly is getting so hot and second, yeah the 6700HQ is going to be hotter than the 3610QM by a good bit and the 4800MQ depends on the clocks and the voltage each run at.

You can also repaste with liquid ultra which will drop your temps a good 10C easily if your heatsinks make good enough contact (I don't know how they have been on that particular machine).

 

HWiNFO is a bit confusing. To many parameters. I was using speccy. Weel they claim they put IC Diamond paste when I buyed it. never heard about liquid ultra. Is that type of paaste?

 

Liquid ultra is liquid metal used as paste.

 

Bah cant find that one im Mexico city. Eaven if I do I dont wanna apply it my self

 

HWiNFO64 is the gold standard. Just put it in sensors mode and leave it running and if you have questions about what's what, take a screenshot and post it here and we can tell you what it is and what is safe, etc.

Liquid Ultra is definitely not for the squeamish but if you're careful it's not that difficult to apply.

If it wasn't for all the import taxes and such I'd recommend you just get a second bottom case and look into modding it for better airflow. The results people have gotten who have done it are quite remarkable.

 

So what you sugestin is to make a mesh on botom of the case? Something like alianware has on ther cases?

 

Some people have done it, and it seems to help. There are different threads with people talking about the work they did and the results. But yes, it would be worth getting a second bottom of the system if you are looking to try it, in case anything might break on it when you are modding it and you wouldn't want to affect the warranty on your system.

 

I like the idea. Any tutorials out there? Cuting plastick corectly is not an easy job

 

I don't think there are really any tutorials that I have seen for that model. I suppose it would be just looking for how others have done it and see what their thought was on where to put the vents and how big.

 

Talk to @deadsmiley he did it with his machine with amazing results.

 

Does it solidify after the application? If it doesn't, it seems kinda risky to use a conductive TIM on something that'll see all kinds of motion and vibrations from transport and whatnot.

 

So long as you don't use too much and apply it carefully it won't move around due to surface tension. Care is certainly needed.

I tend to use a dremel to make basic cuts in plastic and then a file to clean the edges.

 

You put the beads in the center of the die and heatsink and the rest sticks via adhesion. It's not really going to move around at all once it's in place. It eats aluminum though so you have to be careful not to get it on anything but the heatsink. You paint it on the heatsink first and then paint the die. A tiny little bit goes a very long way. If you're worried about getting it on something other than the die, electrical tape to cover exposed components works. Seriously though if you're careful and patient with application the risk is minimal.

 

I tend to spread it in the thin layer they advise but it's a VERY thin layer and i've ensured my heatsink is very flat.

 

When I had it on my CPU had to do a bit more than a thin layer but it didn't move at all. I just used the brush to get the beads into the middle of the die but when I removed my heatsink it hadn't moved at all and it was a fresh paste job since my 880M gave out like a week later.

 

I was thinking. Its posible to cut case and ad wire mesh. BUT. Since we use pad cooler he is going to blow all the dust in side a machine. So I dont think its so good idea.

 

You will potentially have to clean it out more often certainly. It depends on what your environment is like.

 

environment? OMG. Mexico xity is so dusty. Never been in dustier place. In 5 min. you can colect dust with fingers

 

Well then you have your answer, you will need to be careful.

 

Was thinking to buy vacum cooler for cpu side. But not sure if he can damage existing fan inside.

 

It wont damage the fan, it's more how effective it will be.

 

OK> I will buy one to try. Some people claim it is lowering temps 5-10c

 

I tried it on one and it had no impact (an MSI GS30 for reference) so YMMV.

 

Well I will try its not to much. Mybe like 20-30$. If it works good if no, I will use it as fan

 

guys do you have idea why Control centar doesnt work anymore? Since I got Laptop from repair Control centar doesnt work. I tryed reinstaling many times. Its just geting errors

 

Get some Gelid GC Extreme or IC Diamond.. That is good enough tbh!

 

Are you getting any kind of error message when you are trying to install control center? Where are you downloading it? Did you use it off of the disk that came with the system? you could try using the version from Sager's site or from Clevo's site possibly.

 

It is instaling normaly but it doesnt start at all. When I try to start it manualy I am geting ControlCenter stoped working. I downloaded new version from Sager.

I know that the stock bottom cover on the Sager NP8278 is too restrictive for good air flow through the heatsink fins. Anything that can be done to increase that airflow is going to help.

I cut holes in the bottom cover right over the fan inlets and that helped a great deal. I did some other things too that really helped. Since a worker knocked off my laptop onto concrete and broke some of the plastics I decided to cut out the plastic "grate" on the back of the laptop where the hot air vents out. It was busted on the CPU side anyway. I use my laptop for work and gaming. It has been beat up pretty bad and isn't pretty anymore but works perfectly.

Nice job. But for me is not going to work. To much dust all around. I buyed OPOLAR vacum cooler. It is so powerful.. DAmn tems are lower on full load by around 8c. Just hoping its not gonna mess with fan inside

 

Hmm... I'd be careful with vacuum coolers... Internal fans spinning faster than they should (forced by the vacuum) tend to cause issues.

 

That worries me also when it comes to this cooler. It's good that it has a speed adjustment; maybe a low setting is safe and still useful for exhausting heat.

 

There is no real test or some kind of proof that is safe. Lower speeds doesnt do nothing. it is same. Bah. Am doomed. Cant instal controlcenter, cant use vacu. Damnnnnn

 

Short update. After allmost 2 months of SAGERS magic repair, NP8677 is getin worst.Its reachin 98-99c after few minutes of rendering.

 

Here's the thing, heatsink assemblies don't degrade in 2 months, and unless your fan has failed, which it hasn't, its also not the problem.
The only remaining explanation is that you're putting so much heat through the thermal interface so constantly that its breaking down the thermal compound. Best thing to do is repaste and make sure the heatsink assembly is properly attached.

 

Check the paste job and for dust build up certainly.

 

nah. Repasting and cleaning doesnt help. Same temps. Whats eaven worst am geting grey screen in midle of work and hall pc go mad, geting errors that ther is not enough ram memory.

 

Are you sure the heatsinks are making contact? You may want to get replacement heatsinks and see if that would help, or possibly lap your current heatsinks with sandpaper. 98c is definitely not normal and I haven't had temps like that since I had a Dell laptop.

 

ayayya. Dont tell me replacemnet again. I invested to much money on this Laptop. I was back to 82-85c when it came back from Sager repair shop. I am thinking they done full check and everything is in order. It past like 2 months . I cant invest no more money in him

 

I'm not saying replace the entire laptop, I'm saying replacement heatsink. Maybe they could do an advanced replacement and send you a new heatsink, then you send back the old one.

 

THX for advice but am not spending more money on him.

 

That's not what I'm saying, I'm saying they might be willing to do an advanced RMA/replacement of your heatsink (not sure if they would be willing to or not), which shouldn't cost you anything.

You could also try lapping your heatsink with sandpaper although it is not officially endorsed.

Lapping your heatsink + using CLU (Coollaboratory Liquid Ultra) thermal paste should in theory help your temps. Or you could just live with your 80c temps, because it honestly would take a while for your CPU to die from those temps, even though they kind of are on the high side.

 

Eaven if they wanna do it it would cost me 300$ more to sen it from Mexico city to USA. I wouldn like to mess with it. It can get worst. Well I wouldnt be wory if it was 80c. Its 95-98c and 60c in idle.

 

That's not what he's saying. He is saying that perhaps they would send you the heatsink assembly (the part, not the laptop) itself. No need to send the entire thing.

That said, I've never seen people complain that temperatures are bad after 2 months of it being good. It's usually bad temperature from day one, and it'd be consistently bad, and nothing fixes it (which points to a design problem). But since you've had good and stable temperatures for quite some time, I think there's something amiss here.

Also, sending the laptop out for repairs is not investing money in the laptop. The investment was the initial purchase, and Sager stands behind their warranties. If you didn't want to deal with international repairs (and the shipping fees associated with such), why did you buy it from a dealer who doesn't offer an international warranties?

 

As I said before temps where high since day 1. Over 80 c.Over time started to get worst and worst. Am in the state where 3d rendering is allmost as imposible.In less then a year of use.
Thing is I had many Laptops before.I used them for same things, but I never had need to send them for repair. I was thinking that same rule will apply with SAGER.
