I've been unhappy with temps in my rig for a while, both stock, and overclocked. When I first fitted this TRUE te,ps were pretty good.... around 80ish under a linpack test @ 3.8GHz.. but it's been creeping up, and up lately... so I took off my TRUE, reseated it, and applied fresh paste. It was then back to it's temps it had when new. Why should this be? Well.... here's why.... It's as flat as my left testicle, that's why! When first applied, the fresh paste bridges the gap.. and when cured up to temp, it obviously flattens out towards the surfaces leaving a HUGE gap!! Look at it!! It would take a week to lap that flat with sandpaper!! I'm horrified at the utter crapness of this heatsink considering it's price. Anyone else had such issues or have I (as usual) bought a crap one?
I've never seen a True that wasn't rounded. They all ship that way, Thermalright claims they perform better that way. But once you lap them they perform Great. I have a std. True and a Copper, here are a couple of pic's of my lapped bases. Standard True True Copper
Thats just ridiculous then. I've just googled it and there are so many people complaining about this. Thermalright reckon it's better that way as it is supposed to match the CPU.. LOL.. yeah right... look at my photo... does that in anyway match the CPU? What they really mean is "We've been told by our accountants to save money, so we can't be arsed machining the base flat, and then we'll tell you a load of crap to pull the wool over your eyes and convince you that we know best.... you poor little retards". Well I think it stinks. I can't believe so many "trusted" reviews didn't pick up on what is clearly, and indisputably, a flaw.
Maybe they were sent specially-flattened samples for review? Maybe it's just that the first few were nice and flat and as time's gone on the company have started to skimp to maximise profits? Give it a lap, even being a little flatter will help. Besides what do temps matter as long as it's stable?
lol yeah pookey, usually with a true you'd lap your chip and the true flat- they are slightly convex by design- if you lap an intel c2d you'll find them concave- this is supposed to fit into that is my guess also you can put a penny or tiny nut into or over the hole on the top of the sink (the bracket clamp goes into) to apply more pressure
they are all like that.. thermalright said it's by design and if you lap it you've ruined it if you lap both the chip and the sink though your good to go- my guess it was done cause the c2d's were concave
Because my temps creep up over time as the paste cures. There's a 0.8mm gap at the edges... you can't expect that to stay "bridged" with thermal paste! It WAS stable... I started getting crashes today, and it was no longer stable under a linpack test despite me changing nothing. Temps are now 10 degrees higher than when I first fitted it. I refitted it, applied new paste, and back to how it was when new. I can't keep removing it and refitting it every few weeks, yet if I lap it I void my warranty. This sucks. From what I've been reading, replacing it will do no good, as it seems that Thermalright PURPOSELY made it convex to fit the shape of Core2Duo heatspreaders, and didn't change a damned thing for the 1366 version, despite the i7 being relatively flat. If I have to spend my afternoon scraping this piece of crap up and down varying grades of sandpaper and voiding my warranty just to get it to work properly, then it's failed in the purpose it was made for. I'm very disappointed in this heatsink.
Mine was like that, temps were awful. I gave mine a very rough lapping, only to 600 grit, but when I re-applied I used loads of thermal paste as well. That knocked about 30 degrees off my temps: http://forums.bit-tech.net/showthread.php?t=150005
Well.. no point arguing with thermalright, or even exchanging it... I'll just have to lap it and void my warranty. Last time I buy a Thermalright product. THAT.... is a joke. They can't even defend the Core2Duo "concave" argument, because that you see above is a RIDGE that runs the entire length of the heatsink base... it wouldn't even mate properly with a concave chip. It's shoddy workmanship by a company run by accountants. I wish reviewers would pay more attention, and I wouldn't have even bought this piece of crap. I'm sure it's great once lapped... but that's not really the point, is it?
Another way in which the Titan Fenrir conquers the TRUE, it seems. Maybe the days of this might cooler are over.
Well.. I will post up temps tomorrow after I lap it. If it fixes the problem, then all is well.. I just think it stinks that you have to do that in the first place, as I'll have no warranty. Fortunately, something that has no moving parts isn't likely to "break".
It means you get a lady to come and dance for you.... and it takes your mind off your temperatures ...and in case you were serious... it means gradually flattening the surface by sanding it down against a known flat surface beginning with very coarse sandpaper, and then progressively finer grades until it's polished dead flat. http://metku.net/index.html?path=mods/lapping/index_eng
I'm a watercooler myself, but everyone who has a TRUE raves about it. I wonder how widespread this really is. That is a ridiculous curvature, lapping will probably do a lot of good!
Or prolimatech! im thinking lapping the true would be a great idea. some reviewers say that the concave base is a good thing. but...
