Toshiba Qosmio X505 Upgraded processor, overheating issues.

Hello, I upgraded the i7 processor that came with the laptop, it was an i7 720qm now i have put in an i7 920xm, i am experiencing some overheating issues. my idle temp is 63-65 Celsius. I used arctic silver thermal paste and made sure that i pasted it properly. Can someone please help me with this problem. I would very much appreciate it.

 

A member by the name of Scanner has upgraded his q898 from a i7-740 to a i7-940xm. I think also a member named Imglidinhere has also tried this.
Hopefully they can chime in soon to help you out.

Hello, HaPPPPPPPPPPPPPPY NEW YEAR,

OJPM,

I think your idel temps are normal. The first thing I noticed when I installed my i7-940xm, was that it ran hotter. The bezel above the keyboard was a lot warmer than before. When the lappy is first turned on my temps go from low 50s to low 60s just surfing the web, or just leaving it on. I do hear the lappy fans spin on quickly. When Im gaming the lappy temps are usually in the mid 80s (88 is high for me). I did reach 90s once, and had the lappy shut off (really hot room, heat was set to high--wife!). Other than that, I've never had a problem. I also use Coolmaster CF storm cooler (turned full blast) when I game. I've played as long as 4hrs (ME 2 JUNKY), bring on ME3, without a problem. I would say as long as your not going into 90s while doing anything, your fine.

I used IC Diamond 24 paste.

 

my cpu temp does reach the 90s hence the shutting down of the laptop. i have turbo boost off and still this happens. may be i should try the thermal paste you used. I don't use a cooler though.

 

It's worth a shot, no guarantees. High quality paste has been known to knock as much as 10 degrees Celsius off of temps.

 

Is there a difference between the ic diamond 24 carat vs the 7 carat or is it just the size of the syringe ?

 

Also Scanner did you spread the paste or did you just put a pea sized dot in the middle of the cpu ?

 

I totally removed the old paste from both the CPU and GPU. I spread the paste like peanut butter on a sandwich (thick and too much). At the time I didn't know any better. BUT, I did not get any paste on anything that it should not have touched. I believe I went overboard with the paste. Later, on I read those articles about pea size drop etc. (OOPS)


Do you think its possible that your pea size drop was not enough?? I spread my paste corner to corner, like knife on sandwich, and then wiped away the excess (like peanut butter).

Also, make sure your fan is at full speed. First I forgot to reconnect the fan, then I had wire rubbing against it-good thing I'm not surgeon.

 

The thermal paste you used to upgrade is the best on the market, the only real competitor to IC Diamond 24 is Shin Etsu X23-7783D paste. This would be the reason your temps are much better; Neither have a curing time.

Arctic Silver 5 has a cure time of 200 hours. That's not a joke either. Essentially this means that it will perform on the same level as peanut butter. That, again, is not a joke.

I didn't like the temps I got when I installed the chip and took it out. I got the same temps as Scanner, but 90*C constant was around what I was getting, compare that to roughly 80*C when it peaked in games. +10*C increases in games weren't what I enjoyed feeling and I was forced to have it on a table at all times. I never had it shut down on me but I did have it touch the 100*C mark and that was it for me... Out it went and I was done with that...

I found out something that was rather shocking to behold about the 920/940XM line. The 55w TDP is the CPU only. No integrated GPU is on this chip.

It goes like this:

i5-430M to i5-580M --- 35w TDP; 25w CPU + 10w iGPU
i7-720QM to i7-840QM --- 45w TDP; 35w CPU + 10w iGPU
i7-920XM to i7-940XM --- 55w TDP; 55w CPU only.

There was a 20 watt thermal design power increase for your CPU. That's the reason for the incredible increase in heat output.

 

[removed]. I used AS5 for years with great results. The cure time might give you 2-5C lower temps but I never measured but got same temps using ic diamond in a later repaste.

I would like to see the OP post a screen shot using hardware monitor showing the package current when idle.

The TDP is for max amount of cooling needed and certainly not needed when idle. To the OP, is this a new or used cpu?

 

Arctic Silver 5 is a Polysynthetic Silver Compound. Meaning, it conducts electricity and is not recommended for most users; If it touches the bare motherboard at all, it's game over. For the higher end segment, it performs, after cure time, equal to Shin-Etsu X23-7783D. Before cure time, it's not that great. I stopped using it since 200 hours is ridiculous. Look it up on the main site. 200 hour cure time. This is not new information. Grats if you get good results from it but contradicting my post [removed] without any real proof of your own doesn't really make me take a step back anymore.

I wouldn't use AS5. GC-Xtreme is fairly high quality and performs roughly on par with Shin Etsu compounds for a drastically lower price for the same amount.

 

Sorry, not trying to be mean but you simply do not know the facts. AS5 will NOT conduct electricity. This is the same irresponsible stuff that goes around public forums, no offense.

Please go to the AS5 web site [removed] and see how conductive AS5 is. Now I use the stuff and I'm not saying AS5 is the best but after trying three different compounds they are all certainly better than peanut butter as you also pointed out.

[removed] please send your comments to
Arctic Silver Incorporated - Céramique 2 under support.

Peace?

 

See, if you hadn't put down that last line in bold, this would have ended [removed]

I will admit I was wrong about the conductivity, however the cure time is real. If you think that this cure time [removed], I'll post this direct quote about the item FROM THEIR SITE:

200 hour cure time.

 

To the OP, sorry for the stupid posts.

I apologize for any baiting. Having used the products mentioned, I find it sad that the same old comments float around from people who just read it on the Web.

LOL, here is a site where toothpast was tested, and after cure time!

I re pasted my cpu and gpu with ic diamond. now my idle temps are 43-45 Celsius that is twenty degrees less than when i had it pasted with arctic silver.

 

Wait... so mayo works better than IC 7!? O__________________O
