My final attempt at cooling my R1. Some thermal compound advice needed.

So I have tried three times now to bring down temps in my R1 after installing two 780Ms. I am not running crazy hot, but I would like to see better results. I tried Arctic Silver Ceramique 2 and the temps were meh at best. I then ordered and installed the triple pipe heatsink from Dell. No drop in temps from that on the CPU. I then repasted with the highly recommended Noctua NT-H1 compound. Temps were the same as Ceramique 2. So I am going to try a final round with IC Diamond. I see there is a 7 carat and a 24 carat version on Amazon. Any difference and which would you recommend? Thanks guys.

 

No difference in the paste itself... the 7 vs 24 is only the volume of paste in the syringe (24 carat is the larger syringe). IC Diamond is the only paste that I find to be effective. Let us know how it goes.

 

I used the 7 carat! Sorry i didnt include that in the PM

Be careful though IC diamond needs to applied a unique way if its not it wont preform to its best.....if you go to the companys website itll show you

 

ICD , Phobya HeGrease Extreme or MX-4 are the best compounds to go for, go ICD, and you surely wont be disapointed! Just make sure apply in a proper manner!

Good luck!

 

I use the line method, which is also what the paste manufacturer recommends. Don't try to manually spread it or you will likely not be pleased with the end result. All little more is better than not using enough. Too much makes a mess and wastes paste. See detailed guidance in the link below.

I agree with Mr. Fox. Spreading the compound can cause air bubbles or small traces of contaminants, which is no bueno.

 

IC Diamond is probably the best thermal paste on the market.

 

LOL, that's true. No bueno. xD
I will repaste soon, will give IC Diamond a chance this time

 

I cannot find IC diamond locally in Aus, next to impossible and amazon/ebay, well the less i say about them, the better.

Currently using AS5 and its giving me good results. One day, i will surely get my hands on IC diamond

 

AS5 will do a good job still. I know what you mean about Ozzy retailers sucking. If it makes you feel any better I still had to order IC7 online in Japan.

 

Here are a couple of quick benches with nothing for cooling but the internal fans at 4.7GHz with a fresh dose of IC Diamond. Nothing like a fresh paste job to make you feel like a little kid on Christmas Day.

 

I got no issues ordering online, infact I prefer it, but customs guys are idiots here in Oz, Auspost guys are pure stupid, sellers don't want to post to Oz, then comes the issue of local retailers hell bent on raping us on prices and then having the nerve to pretend business is bad.

 

I just recently started using Coollaboratory Liquid Ultra

Coollaboratory Liquid Ultra - top performance for High-End systems!

 

Any difference in temp, before and after? Have you ever repasted the Liquid Ultra? Does it seep into the copper? Seems like one needs to lap the copper plate/use metal polish to get rid of it from the copper.

 

Line method for the CPU, but what is recommended paste method for GPU? Pea size dot? Thanks.

 

A pea sized dot for the GPU would be about right. Just make sure you use the correct amount.

 

I really want to try it and was going to buy some but I've been reading about how it literally sticks to copper like poo to a blanket. I may just keep on with IC

 

Imagine the smell when it heats up.

 

The cross method spreads better, but it's easier to use more than needed with this method. It took me two re-pastes to finally figure out how much was perfect for the GPU using this method with IC Diamond. Every paste spreads differently, too. Some more than others... That's also something to take into consideration.

The pea method or cross method are the best for GPU's.

 

Running Prime95 for 10min at 4.4Ghz across all cores the temp was in the mid 80's

 

Sounds good but what's the CPU package power during benching? Without that data "mid 80's" is quite meaningless I'm afraid..

HWinfo, XTU, Throttlestop are all capable of reporting fairly consistent power readings.

 

Why would you say mid 80's is meaningless. I get no CPU throttling as the temp is low. I'll run it again later with one of those programs and let you know. Though in my Bios I have my settings at 99/56/99 ,with a Flex Vid of 0 for all cores set at multiplier of 44.

 

Whoo very promising indeed I already miss Ivy Bridge :thumbsup:

Initially when you only said "mid-80's" and Prime95, I was thinking maybe the power limits aren't set high enough to get hot. But with the rest of the info it all looks well and good. No throttle at 44.. Puts Haswell to shame

 

Has(not so)well PWNED

 

Finally applied the IC Diamond. Dropped the CPU a few degrees The 2960XM never hits 90°C in the XTU CPU stress test anymore since applying ICD. The 780Ms idle a tad cooler, but run around the same temps under load. First screen shot after running 3DMark11 and second after a five minute XTU CPU stress test. Notice my increased CPU temp in XTU also raises the GPU temps a bit. The 3DMark11 test is with 780Ms OC'd at offset 128/307 with no voltage increase and the 2960XM at Level 2 BIOS OC. XTU is 780Ms at stock and the 2960XM at Level 2. Used the dot method on the GPUs and the line method on the CPU. So does this look about normal?

 

When I did the repaste with my late R2, I didn't see much improvement in temps which led me to believe that "maybe stock Dell paste ain't that bad.."

Recently my CPU temps for the 4930MX has been out of control. The final straw was when a power consumption of 70W (Throttlestop bench 1024M 8-threaded, multiplier 40, 1.15V) resulted in thermal shutdown within 10 seconds So I got some paste (Tuniq TX-4, mainly attracted by the claimed "good low-pressure performance") and did the usual.

The moment I turned the computer back and started throttlestop, I thought something was wrong. The idle temps were around 38 C?! I've very rarely seen sub-40 and I guess nothing's impossible with a fresh coat of paste. The same benchmark now heats me up to 85 C, completely without issues. Time to see if the GPU temps have improved..

TLDR: scrape of that crusty stock paste and apply your own if you want good temps (but I guess you already knew that )!

 

70W 85C, sounds about right. What's your ambient temp, in Celsius?

 

Ah should've included that.. Thermostat's at 68F so (68-32)/1.8=20 C (doesn't feel like it *teeth chattering*)

 

Hey Mr. Fox. I am guessing that by you liking this post you think these are acceptable numbers. This was about my fifth time tearing down the R1 and unfortunately my keyboard plastic frame (which has the power button, etc.) finally said enough is enough and spit out one of its tiny plastic clips at me. I am very careful, but man those clips on that frame are microscopic and fragile. Luckily I have a 3 year accidental on my R1 and Dell had me a new one in 48 hours at my door. I will never buy an expensive piece of kit like this without full accidental and this proves why. Excellent turn around time on Dell's part and I do not have to send the broken frame back. Thank you Dell!

 

Yes, those are nice temps... good job on the repaste.

Those little plastic clips are pretty fragile. I agree on the warranty service, too. Can't beat it. :thumbsup:
