| Thermal Grease
I'm getting ready to install:
Intel Core i5-750 Lynnfield 2.66GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor
»www.newegg.com/Product/Product.a···19115215
In the past I have always scraped off the grease that comes with a stock heatsink and used AS5. My question is - I don't OC so is the stock grease they use now OK for installation or should I continue to use AS5?

| If you're not OC'ing the stock thermal compound should be OK.
I would (personally) use the AS5.
FYI...You dont Scrape the compound off.
Use 90% Iso Alchol to clean it and a soft lint free rag or coffee filters work well also.

| I was using the word AS used to use on the old P4's.
BTW - anyone using AS5 on this particular CPU should be aware that you apply the grease using the i7 instructions NOT the i5. If you notice the notches on the core are aligned in the i7 fashion not the i5 even though it is, in fact, an i5.

If you applied the grease in the i5 fashion one would conclude you would probably not experience the best cooling.

1 edit | My rule of thumb:
I use AS5 in situations where there's little to no risk of the grease (since it's capacitive, unlike the generic "white thermal paste" you've seen elsewhere; I don't want to risk shorts). Mostly I use it on CPUs.
Otherwise I use Arctic Silver Ceramique, mostly on GPUs and chipsets. If I have any doubts using AS5, I choose Ceramique.
I haven't tried Arctic Alumina.

Well, I cleared the grease and applied AS5 like the instructions said knowing that the instructions for my CPU should follow the i7 and not i5 because of the notch alignment and my core temps are all pegged at 85-89C which is utterly unacceptable. I cleared the CMOS settings, used Optimized Default in the BIOS (like the manual said), and I'm still pegging. What other option do I have except removing the H/S and applying the AS5 in the manner shown for i5's but against the illustrations for the notches?

I resat the heatsink and turned the paste around and now I'm running 44-46C on all four cores so I'm thinking I probably didn't get the H/S sat right the cheap pieces of sh...
... any recommendations for an i5 heatsink? I don't trust this and want to reseat it with a good one. I've never bought an after market one before and size shouldn't be an issue (I have a full size case) but I don't have unlimited funds.

Some of the 1156 boards allow you to use LGA775 CPU HSFs'. I'm thinking of building another system using the EVGA P55 FTW mobo.

FrozenCPU has quite a few heatsink's listed that will fit that socket. I'm partial to Thermalright heatsinks. High quality and good performance.

If you are finicky about thermal management I guess the true answer would be "yes" use a better compound such as AS5, properly applied.
However, if you are not OC'ing, there really is nothing intrinsically "wrong" with the stock HSF and supplied/applied compound. Keep in mind that this was developed and tested extensively to work with the CPU. Yes, it is meant to be a cost-effective HSF, but at the same time, Intel is not in the business of shooting themselves in the foot, by coupling a cpu with an inadequate cooling solution!
Remember, the vast majority of their cpus will never see anything but the stock HSF and attached thermal compound...for well over 95% of these cpus, there will be no other solution for the life of the unit!
IMHO, if you are not OC'ing, then the stock solution is quite sufficient.

It's a matter of trust. I've never had any problems with stock coolers in the past but I think these Intel ones they been using on the multi-cores are pretty shabby. Like I said in my first and second post I always use AS5 and have never used anything else and I think 44-46C is fine. Just any of you builders out there that decide to use this CPU beware that Arctic Silver's instructions are contradictory.

| this is my method of applying AS5 on a multi-core CPU
first of course is cleaning the CPU heatspreader with denatured alcohol
second I apply a very very thin coating of AS 5 covering the entire heatspreader. think thin to the point you can almost see through it.. it's done with a razor blade and it takes some practice..
third I apply the AS 5 in a cross pattern, making sure the bead is very thin. each line would be about 3/4 the length of the heat spreader, centered of course..
lastly, prior to installing the heatsink, clean that too with alcohol, and with a very soft cloth polishing the contact to a mirror finish (or as close to one as possible depending on the h/s)..
this has not failed me with dual core and quad core CPU's.. I currently have a Q6700 quad core overclocked to 3.4GHz.. these are my temps:
IMO with the "hot" core at 30C idle and 53C under load is not bad at all with air cooling - using this cooler: »www.newegg.com/Product/Product.a···35200026 which I think I paid $25 for..
Next week I'm upgrading to a Core i7 system, I plan to use the same method with that as well, so will post those results once done.. |

If you look at the pic it shows mounting holes for both 1156 and 775 HSF's.

i always use TIM on my builds but if the stuff that comes on stock HSFs didnt work as intended @ stock speeds, it wouldnt be on there. |

Hmmm... interesting. I, in a past life, worked at a place that had tons of 99% IsoAlc so I availed myself of that to the point I have enough for the rest of my life. Is this something you came up with or is this a common application practice for i5/i7's? My temps on CPUID are exactly the same as yours. |
