My problem and specs are listed below, I basically want to know how to cool my CPU down, I seem to have a lot higher temps than others with the titan fenrir

Room temperature... I don't have anything to measure it, but it is a hot day
CPU temp under prime95 up to almost 90 with about 80 avg, with 4ghz can reach 100 with about 90 avg (temps on full load with prime95)

Idle temps are around 35-45

Foxconn Flamingblade GTi
i7 920 D0 (BCLK @ 170 only, vcore + 10mV to default)
Corsair XMS3 6GB (3x2GB) DDR3 PC3-12800C9 (1600MHz) Tri-Channel (currently on sale, running at 1363 with latency 7-7-7-20 @ 1.65/1.66voltage(shows different in some programs)
ATi 5850 (default at the moment, but stable @ 900/1150 stock voltage under 80 degrees)
Coolermaster Storm Scout with 3 standard fans
Titan Fenrir (fan is facing the top of the pc, as it seems coolest in that direction)
Artic Silver Cerimique.. and then added some of the titan royal grease when changing direction, also seemed to help
Also got a soundcard and wifi adapter installed

Software I have installed and ready:
Core Temp
prime95
CPU-Z
3D mark 03(not newer versions yet)
Aegis Panel Ex

For GPU:
MSI afterburner
MSI Kombuster
GPU-Z
GPUTool

Hmmm. The Fenrir needs a little more thermal grease than a normal cooler to fill the gaps between heatpipes, as it's direct contact. I'd try mounting it again, with the fan blowing through the heatsink towards an exhaust fan, and with more thermal paste than you've used (or maybe less if you've used heaps!). Apply it using a blob in the middle, don't spread or you'll probably get air gaps, especially in this cooler.

I used all of the thermal grease lol, it was evenly spread, and then the second time I added a blob in the middle, it didn't come with much, but still virtually no difference, I could move it again, but it would be resting on the ram which is already hot, I have moved the fans about quite a lot and this seems the best at the moment, I'm thinking a new cooler just a more powerful fan

EDIT: OK so basically I just took the side off, temp only went down by about 2, and I shoved my hand in the case, my case fan at the back seems really weak so I am going to assume that the others are too, the air coming out the other side of the fenrir is still cool

Prime95 is on now, temps are 84 highest, 32 lowest, 80 avg

I was going to point you to this thread, but the images have gone for some reason.

If you've used it all, you've used way too much. You're looking for a blob just bigger than a grain of rice on the centre of the CPU, perhaps a tiny bit more for this cooler. Once the cooler is down, don't lift it back up again or move it too much other than tightening, as this will create air pockets. Also, make sure you've thoroughly cleaned the old paste from the chip with isopropyl alcohol or dedicated cleaner before you apply more (or indeed any).

Damn, compound instructions said to apply evenly so I just used it all, I assume that it came with the right amount then, it would be about 2 grains of rice size, 1gram, whilst I used 2.5 gram arctic silver + the royal grease
 
There are lots of threads on how to best spread the paste all over the net. Here's a short one for starters. I suggest your search for your cooler and see what people are getting the best results with, as there are different methods. You will also get an idea of just how much to use.

Too much compound becomes an insulator, blocking the contact between the IHS and the cooler.

Yes I see how now, do you think if I basically scrape it off that it would at least be better than it is now.. until I get some more to use properly?
 
Once contact is broken after it having been used, it may even be worse than before. Get some new paste and isopropyl alcohol and do it properly is my advice. The machine is usable for now at least.

I'd hope so... I just bought it yesterday.

Went to buy new paste and alcohol, cleaned and redone.. pushed it hard, tiny bit came out one side, that ok?

Still got max temps of 84, avg of about 80 with prime 9, lows of 28-33 when idle
 
As long as the bit that came out isn't splodged all over your motherboard, it's probably fine. It does indicate you've put a tiny bit too much on, but let's not worry about that for now.

Your idle temperatures are normal, 84 is high still however. Stupid question - did you connect the fan to the motherboard? Could you try connecting it somewhere else? Can you also put the CPU to stock settings? Something's still not right.

I could try to connect it to somewhere else with an adapter, which I could get tomorrow from an older computer, however I could just find out the RPM.

Although the settings aren't much different to stock, I will reset back to normal anyway, and get idle, and prime95 temps..

Oh and yes it is connected but some people have said their coolers work better with a direct PSU connection.

The temps are high when running, but the second (literally the second) I stop the test it goes down to 55ish, next second, 45ish and then next under 40.. next few seconds goes back down to idle temps

I noticed the voltages were changing in Aegis Panel and CPU Temp when running, not just below the stated voltage, but up around 1.3ish when it is currently set at under 1.1, seems like it is compensating perhaps for stability or something? I am new to overclocking, but I know that if I don't raise the voltage at all and I go over 160 then it simply doesn't boot, even though 160 is stable, I would go for a higher stable overclock, starting from scratch and slowly overclocking, etc.. but so far not risking it with the temps.

Aegis says 2256RPM cpu fan

Temps:
NB: 33
System 49
CPU 32

Bear in mind the cpu is at less than 1%

All fans are on max in bios (possible problem?)

I don't know where the sensors are or what NB even is..

The fans have LED's on, connected to a button at the front, I turned it on, no change to RPM, so I don't suppose it will be the cause at all, air in the case seems pretty cool

Doing a quick prime test now... Aegis is saying..
NB - 33
System 49
CPU - 72,73 not really changing
Vcore is up to 1.286.. now 1.309 (it keeps changing)

Core Temp 0.99.5 says..
Core 0 82
Core 1 82
Core 2 80
Core 3 77
With highs of a couple over that
CPU is at 3578.54 according to core temp 170.41x21.0

CPU-Z says the same core speed and although changing is has a voltage the same as Aegis says

Another possible program to test true temps? I heard everest being talked about a lot..

I just OC'd my 5850 to 900/1150 with these CPU settings and played crysis warhead on full gamer settings with 1080p, no problems, temps of around 50-65 in core temp
 
CPU core voltage in BIOS 1.243

Core Temp:
Idle 27-33 through all cores

Aegis panel temp:
CPU: 26
CPU Fan 1349 RPM
CPU VTT 1.120V
Vbat 3.104

Core voltage - 0.944-0.970
Core speed 1604 MHz
x 12 Multiplier

TDP 43.8 watts

----------------

Turn on prime95

Vcore alternates but goes up to 1.232
Core temp highs of 65
Core speed 2807MHz x 21 Multiplier
CPU fan 1567RPM
Aegis CPU temp 55 after a while
Core temp average on load 63 after a while
TDP 147.3 watts
CPU_VTT goes up to 1.123V

----------------

Using Aegis panel to raise core speed to 150x20

Core speed 1795.5x12
TDP 43.8 watts
Voltage 0.958
Temps average 30 in core temp
Temps 26 in Aegis panel
CPU fan 1341 RPM

----------------

Turn on prime 95

Core speed 3142.2MHz x 21
Core voltage 1.232
CPU_VTT goes up to 1.136V
Core temp average 65 after a while
Aegis average 58 after a while
CPU fan 1636RPM

All seems stable

----------------

Bclock up to 160

Core speed 3351.6MHz x 21
Core voltage 1.232 (same as above)
CPU_VTT went back down to 1.131-1.134
Core temp average 68 after a while
Aegis average 61 after a while
CPU fan 1728RPM

Memory is up to 1277MHz at this time

All seems stable

---------------

Pushing it 1 Bclock MHz at a time...

Over 166 @ Max of 72 in Core temp, 62 in Aegis
CPU_VTT back to 1.134-6

Blue screen @ 168

Tried raising the Vcore by 10mV and going from 170 like I had it before, but instant system restart

System is back to defaults for now

I'm new to overclocking, so can people help me out with the next stage... what is:
CPU_VTT
QPI_PLL
IOH
ICH10 SB Voltage
Vdroop compensation
CPU clock amplitude ctrl
