Core i5 Problem?

Hi all,

I have been using my PC for the best part of a 6 months now. When I orginally put it together I think I put the CPU on wrong. I believe I posted about this back when I did it and some people on here said that it wouldnt really matter as long as the temps were ok. Well after 6 months of allmost daily usage there seems to be an enlarging cap in the difference in the core temps.

Core temp reports them as follows.


LOW HIGH
Core #0 - 25c 33c
Core #1 - 38c 46c
Core #2 - 33c 41c
Core #3 - 40c 50c

I am learning towards the fact the cooler is not sitting in the ideal position on the CPU and that is leading to this range of temps. I am just wondering if it is actually worth repositioning the cooler in the correct way or is this quite common since I would rather leave it and only move it if really needed.
 
I'd say it's fairly common to notice a slight difference in temperatures but in your case it does seem fairly significant. If you're worried, you have nothing to lose by refittng your cooler. Clean off all the old thermal compound and apply new stuff. I always find a pea sized amount of compoud in the centre of the CPU heatspreader works best and it ensures an even spread under the pressure of the cooler itself. You may as well try this since it can't do any harm anyway, but you also have to consider that a sensor could be slightly faulty or even that this is completely normal.
 
Maybe I should add that they were closer to each other when I first got the PC and it was only over the last few days I noticed they seem to be getting a bit further apart. I actually got do with a bit of a spring clean inside the case as well so will trying an organise some time that I can do it when I havent got three screaming kids around me! thanks for the heads up guys.
 
It seems I am starting to have some trouble with the system. My Razor lycosa will just random power on and off like its being plugged in and unplugged but only when I`m gaming, this would lead me to believe that my power supply is perhaps not getting enough cooling to power the system now? I will attempt to clean it out tomorrow but is there any software that can message the power draw from the power supply?
 
How are you measuring your temps? I mean load temps of 33C on core 0 and 50C on core 3 is definitely not normal if all of them are put under the same load, you need to run something like Prime95 or Intel Burn test to put all of the cores under load and then take readings, you can't compare load temps when one core has been working harder than the other and also the idle differences are largely irrelevant.

It could just be that the sensor on Core 0 is a bit stuck but reseating the heatsink with fresh TIM applied is worth a try if you're comfortable doing it.

Try your Razer Lycosa in a different USB port or on a different controller if possible and update all USB drivers, I would think a lack of power would affect other things long before the keyboard. What motherboard do you have? the Asus range seem to be having all kinds of intermittent faults relating to Audio/Network Card/USB but hopefully it's nothing like that.

Cooling or a weak PSU is very unlikely to be the reason your mouse is not working.

It's either faulty firmware (common with razer mice), faulty wire (where the cord enters the mouse), faulty grounding on your usb port (part of the port/mouse connector is in contact with case) or faulty usb driver (only really applies to USB 3 ports).
 
I always thought in the newer multi core CPUs that had built in Grpahics also that the core neares the dedicated GPU 'part' of the CPU always ran hotter than the other cores if on board graphics were being utilised due to the extra work going on in that zone of the CPU ?

I am sure I remember seeing an article about that somewhere ?
 
I gave my PC a really good clean out today. There was quite a bit of dust under the CPU Cooler fan so I hoovered all that out and I also cleaned everything on my desk including my monitors. I also switched around some stuff into new usb ports and left out some stuff I dont need (USB Web cam) since I think it might actually be that causing the issue. I am still using my PC with the CPU cooler in the wrong place but overall my temps are down a little after the clean and when I can get some cleaner I will change it but atm its fine.

I dont believe my PC even has onboard gfx? I think that is only with certain motherboards? But i am using a 6950 atm and that is in the first slot so I suppose there could be a small issue of more heat on the lower position cores and i suppose this would also not be apparent if my CPU cooler was positioned correctly. I am tempted to get into the world of custom water cooling but i would want to wait a bit for that :)

I thought the new gen i5 CPUs all had dedicated GPUs built in anyway, but I guess if you are not utilising it then it shouldn't produce any heat in the die
