£500ish for a friend.

All the bits were in stock when I place the order yesterday but they haven't dispatched today.. :cry:

(Haven't built a pc for a while I'm looking forward to it!)
 
Ok so I need a little more advice...

Typical!

I've built this pc, removed the stock thermal paste and used some arttic silver 5 which I applied to the cpu.

Temp when idle 33
Temp when stressed (prime95 blend for about an hour) 78 with a peak of 90.

So I think this is within the limits and he shouldn't be doing anything that is going to thrash all the cores.

My main question is that the cores do not run at the same temp, in fact the one hit 90(core 2 of 4) while core 4 of 4 was running at 77-78!

Is this normal or was I perhaps too sparing with the silver?
 
What do I do? pull off the paste and try again with a bit more.. I'm always very careful with arctic silver, as it is electrically conductive...

I just put a square on the center of the cpu, but that stock heatsink doesn't seem to put a lot of pressure on the cpu.

Also I installed the 120mm fan to pull air in the front of the case, I could set it to blow air straight onto the cpu from the side, but that would rather leave the psu and gpu with very little fresh air?
 
how much did you put on? you only need a grain of thermal compound...literally grain-sized
re: the fans...the 80mm fan as exhaust and the 120mm in the front as intake is absolutely fine, the psu doesn't need much air (mounted fan up or fan down). the gpu should be fine doing its own thing too

my feeling is that you haven't mounted the cpu heatsink properly. it needs to click down. i'm running a 3.0ghz i5 3330 at 3.3ghz with a very minor voltage bump and temps don't exceed 70c on the stock cooler

I had a similar issue when I tried to replace my i5 stock cooler with an aftermarket Zalman, but that one turned out to be bent so it wouldn't go back on. So I put the stock back, with an old tube of Arctic Silver. I did notice that the paste wasn't the same as when I bought it new. It had separated, into a clearly transparent liquid and paste.

Tried a pea-sized bit with the cooler pressure to spread it, but this led to load temps much higher than with the stock Intel compound. Hitting 100C under benchmarks! So my conclusions were that the Arctic Silver had not 'aged' well in the tube in a cool dark cupboard for a few years, leading to it separating out and not spreading properly/conducting heat properly.

80C sounds about right for this CPU. 90-100C with the stock cooler probably means the paste hasn't been applied properly. After my issues, I don't really rate AS5 anymore, and would recommend you give MX2 a try?

I have something else, but my silver is not sepparated and I replaced the paste on my old graphics card with it a week ago and it dropped the temp well. I guess I need to reseat the cooler tonight... :)

I remember first time I used AS5 it dropped temps significantly below stock, but this time was a disaster. I think it works well if applied properly but it has different fluid flow properties to some other thermal pastes so it doesn't respond well to certain spreading methods.

Give reseating it a go, try using the other thing you have or a big pea size AS5, and make sure to give the cooler a squeeze/tiny wiggle round once seated, before clipping in.
 
Yeah I tend to do a halfway between spreading and pea, a squares blob in the middle, maybe I had too much maybe too little. I'll give it another go. While spreading my square blob I noticed it was getting quite difficult to spread.

I also hate these 'clip on' heat sinks. I never fell like they are on properly..
 
More worries, Arctic silver has a 200 hour "break in" time!!! So do I need to repalce it or not :S? I think I could do a much better job this time!

What do we think?
 
I have reapplied using the verticle line method as the arctic silver website says too and in place testing on prime 95 has hit 88 with in the first 10 mins... I have some mx-3 but I'm really unsure it will be any better than the silver?
 
Ok so 20 mins in and that peak was the peak, Peak temps across the 4 cores: 85:88:84:81

But the temp wonders up and down as far as 72 for the package and then back up and then down again... I'm a bit WTF about it all!?!?!?!?

Any ideas? Do I need to raise a ticket on the cooler?
 
1 hour in and the peak temps are package:88 (86:88:85:83)

But it still wonders about a lot, at the moment 74: (73:74:72:69) I've never seen temps move about like this underload!

Is there something funky in the i5 that i'm unaware of?

Stopped thes stress test and temps back down 2 mins later to 39 (38:39:38:36)

Do I try my mx3 or is it ok? I know it is running hot but...

If it is too hot then the stock cooler is either damaged, or not fit for purpose! (Or I'm just too generous with the silver)
 
I was going to do a test while gaming, especially as he games, kerbal, civ v and minecraft... lol But my wife came in with a galss of wine wanting a chat and now it is late and I have a 3.5 yr old and a 1.5 yr old that will drive me nuts in the morning...

sigh.. maybe one quick round on war thunder.. just to test right?

War thunder, cpu package 53 gpu 63... no problems there really...

Yeah, that sounds about right. I believe Kerbal is a bit more CPU intensive, so if you have time later to quickly check that then go for it, but equally if you can't be bothered I'm sure it'll be absolutely fine as is. Those are roughly the stock cooler gaming temps I got.
